Electrostatic Lab Investigation #1: Materials: - fur - plastic rod -wool - balloon - electroscope Procedure: 1. The difference between these two measurements, plus the diameter of one of the balls, is the distance \(r\) between their centers. In this section, you will observe the induced polarization of a neutral insulator and the transfer of charge by contact. Wool is a conductive material, which means it readily gives away its electrons. Therefore, to demonstrate the inverse \(r\)-squared dependence of Coulomb's Law, we need to measure the displacement as a function of the separation between the centers of the balls. Their electrons are bound tightly and cannot move. Number of Once you rub the balloon to the sweater, it gathers electrons so that once you place the balloon on the wall it will stay up and attached to it. Figure 2. b. Recharge the metal plate by placing it back on the lucite, touching the lucite, and then lifting the plate off with its insulating handle. Static electricity or Electrostatics David Case: March 6, 2015 Experiment #8 Static Electricity or Electrostatics Objective: To explore the concepts of static electricity and to discover how many types of electrical charges exist and how they interact with each other Materials: After that, I then made him touch the doorknob and all of the negative charges followed through the door. Repeat steps 1. 3 1 m 18 V 12 V/m What do you predict for the answer? Since the rod is an insulator, charge will not flow from all parts of the rod onto the electroscope; you need to touch all parts (except where you are holding it) to the electroscope. Payment is made only after you have completed your 1-on-1 session and are satisfied with your session. This laboratory activity provides the opportunity to investigate the concepts of static electricity, electrical force, charge, and polarization. Record your results.

PURPOSE OF THIS ASSIGNMENT: To improve your scientific literacy and critical thinking What happens? The negatively charged Bring the lucite rod close to (but not touching) the pith balls. The excess amount of negative charge in his body will go through the doorknob as he touches it. By grounding the end of the tube with your fingers, you are providing a pathway for the charges to move. Explain how thes InstructionsIn a two-page paper, identify the physics principles contained within the following scenario. Surprisingly, the exact physics of the process of charging by friction is poorly understood. Electrical conductivity is based on the flow of electrons. 4.Ask Reflect on your answer to #2, write down how your thinking has changed. Have a class discussion. one gets from the charge. Electrostatics, as the name implies, is the study of stationary electric charges. number of positive and negative charges (thus an equal number of protons and electrons). Wool is a conductive material, which means it readily gives away its electrons. Practice taking measurements and compare your readings with those of your lab partner until you are sure you can do them accurately. The study of the Coulomb forces among arrangements of stationary charged particles is called electrostatics. You are going to measure the displacement of the hanging ball. The magnitude of the electrostatic force between two-point charges ql and q2 is given by Coulomb's law. The hanging ball should be at the same height as the sliding ball (i.e., the top of the mirrored scale should pass behind the center of the hanging pith ball, as in Figure 12 below). 12 Test Bank, Chapter 01 - Fundamentals of Nursing 9th edition - test bank, Kami Export - Jacob Wilson - Copy of Independent and Dependent Variables Scenarios - Google Docs, Kami Export - Athan Rassekhi - Unit 1 The Living World AP Exam Review, Greek god program by alex eubank pdf free, Kaugnayan ng panitikan sa larangan ng Pilipinas, EDUC 327 The Teacher and The School Curriculum, Leadership class , week 3 executive summary, I am doing my essay on the Ted Talk titaled How One Photo Captured a Humanitie Crisis https, School-Plan - School Plan of San Juan Integrated School, SEC-502-RS-Dispositions Self-Assessment Survey T3 (1), Techniques DE Separation ET Analyse EN Biochimi 1, The University of Texas Rio Grande Valley. Step 4: Note down the reading on the ammeter. Lab 1 - Electrostatics You must use appropriate significant figures and scientific notation in your answers. Reflect on your answer to #6, write down any new ideas that you have. Have a class Electrons carry negative charge The electric field surrounding a charged object gets weaker with distance, the object will have a stronger attractive force on its closest charges of opposite sign and a weaker repulsive force on the like charges farther away. Lab 1 - Electric Field and Electric Potential Introduction Physicists use the concept of a field to explain the interaction of particles or bodies through space, i.e., the "action-at-a-distance" force between two bodies that are not in physical contact.The earth modifies the surrounding space such that any body with mass, such as the moon, is attracted to it. In an insulator (a material that does not conduct electricity), a charge cannot move very far (if at all). law. when you rub a balloon on wool, this causes the electrons to move from the wool to the balloon's A lab report is an account of an experiment and what was discovered during the experiment. We are all familiar with the fact that rubbing two materials together for example, a rubber comb on cat fur produces a static charge. Slide the block into the Coulomb apparatus without touching the sides of the box with the ball. Use several sentences and perhaps a diagram or two to explain the behavior of the charges in the electroscope. A. If a neutral material is placed inside a weak electric field, it will not experience a net force, In its present form, the electrophorus consists of a lucite plate on which rests a flat metal plate with an insulating handle. where r is the distance between the two charges and k is called the proportionality constant and is You will learn to detect the presence of electric charges and, at least semi-quantitatively, measure them.

As shown in the demo below, the sweater is positive and the balloon attaches to the Electric field lines are typically drawn to visualize the field. differences in the two models represented by the sims. AST 109 Western Nevada College The Rotation of The Sun Lab Report. The presence of the charged object above the plate of the electroscope, induces electrons within the electroscope to move accordingly. Both the negative and positive charges have the same pull/push strength that can affect 4 1 m 24 V 16 V/m Distribution of charges in a polarized and non-polarized object. Devise and execute an experiment to verify the dependence of the Coulomb force on the value of one of the charges. Each metal atom contributes one or two electrons that can move relatively freely through the material. If not then add a title. Electrostatics 1991, - B. C. O'Neill 1991 The Eighth International Conference on Electrostatics organized by the Static Electrification Group of The Institute of Physics, was held at the University of Oxford State Whether Your Experiment Succeeded. What do you predict for the answer? However, if a neutral object is placed inside a strong electric field, the material may become polarized. The total negative charge of the electrons is normally exactly equal to the total positive charge of the nuclei, so the atoms (and therefore the entire object) have no net electrical charge. Physics Lab Report. The experiment used a method known as titration to determine the amount of acetic acid in vinegar by percentage mass. The puck will move horizontally right if both the magnitude and the distance were the same between the two charges. device used for producing high voltages and creating static electricity. In a metal, a charge can move freely and stay on the surface. Using Coulombs law, we can explore the effect of the distance, between two charged Consequently, when you rub a balloon on wool, this causes the electrons to move from the wool to the balloon's surface. always steal electrons from things they come in contact with; others are more willing to give up electrons. Both the negative and positive charges have the same pull/push strength that can affect the positively charged puck and they are different in the way they affect the puck by either pulling or pushing. If the humidity is high, as it is sometimes in the summer, the experiments are more difficult, and some may be impossible.

Coordinate a broad array of scientific expertise: - Manages multiple projects within scope/budget/schedule . If they are charged differently, they show attraction. earth. 4 Pages. The plate actually makes contact with the lucite in only a few places; and because lucite is an insulator, charge does not transfer easily from it. Lift off the top cover and look down on the ball. Connect the 3-phase circuit as shown in gure 1.2. attachment_3. After that, I then The conductor has been polarized, and will now be attracted to the charged rod. c. What do you think would happen if you use 2 charges instead of one to make the puck Coulomb's Law describes three properties of the electrical force: The force is inversely proportional to the square of the distance between the charges, and is directed along the straight line that connects their centers. When charge was transferred to the top, the gold leaves would become charged and repel each other. neutral region) and the support/needle acquires an excess of negative charge (since electrons Turn down the variac and shut the power off. If the negative rod is brought near an isolated, neutral conductor, the conductor will also be polarized. The balls will share their charge, and half the charge will remain on the first ball (assuming the balls are the same size). Although the wall should normally have a neutral charge, the charges within it can rearrange so that a positively charged area attracts the negatively charged balloon. b Record in your notes the relative humidity in the room (from the wall meter) and the inside and outside temperature. negative charges affect the puck when displayed in the hockey game. Recharge the balls as in steps 1 4, and record a series of measurements of the inside edges of the balls. Separate Salt and Pepper with Static Electricity Introduction: Static electricity is the build-up of electrical charges on the surface of an object or material. The puck will move horizontally right if both the magnitude and the distance were the Then bring the rod near one of the balls. In order for the balloon to stick to the wall you need to have rubbed the balloon on the sweater so that it is able to collect electrons, then once you place the balloon near the wall it will stay on it. Therefore the balloon same between the two charges. If high-humidity conditions prevent you from completing certain parts, you may try them again next week with the Van de Graaff experiments. 3) Stick the "T" and the "B" tape to a surface, so that about 9 cm of the tapes are hanging freely in the air.
