This is one experiment with a few questions. I don't mean to break the rules on one question at a time but I wanted to give all the relevant information. I didn't know if this was the right way to ask for help with this.

Experiment 1: Verification of - Behavior of the Coulomb Force Procedure: Initial Conditions: Full Screen, Atomic Scale Page 2 of 6 Lab 16 Instructions/Lab Report: Coulomb's Law Due: See Course Schedule 1.1 Set the values of charges, q and Q each, to + 1e [Note; e = 1.602x10" C]. 1.2 Change the distance between the charges from 10 pm (1 pico-meter is 10 12 meter) to 100 pm in steps of 10 pm and obtain the experimental value of the Coulomb Force between the charges and complete the 2nd column of the Table below. 1.3 Calculate the Coulomb Force based on the formula (sample calculation for 10pm is given below) and complete the 3rd column of the Table below. Use F = 8.988 x 109 9* N with q = 1.602x1013C and Q = 1.602x10 19C. Calculation of Coulomb Force for 10pm = 10 x 1012 m. F = 8. 988x109 1.602x10-1912 (10x10-12)2 - = 230.67 x 10* or 2.3067x10 N=231x10*N F = 2.31x10 'N.

What evidence do you see that Newton's third law applies to electrostatic forces? Answer: 2. How does the value of the electrostatic force vary with the value of the charges? Answer: 3. Coulomb's equation is used to determine the force between two charged bodies separated by a distance F =1914 The variables are k (Coulomb's constant), q (charge of body in Coulombs, C), r (distance between bodies in meters), and F (electrostatic force in Newton, N) a. Using your measurements from the Experiments above, determine Coulomb's constant, k. Show your calculation. Answer:b. Using your value of k, show your calculation for the electrostatic force for the 2 situations below: i. -4pC charge is 3cm from a 5pC charge. Answer: ii. An electron has a charge of -1.602*10-19 C, and a proton has a charge of +1.602x10 13 C. In a hydrogen atom, the distance between them is r = 5.3x10-11 m. Calculate the electrostatic force between these two particles. Show your calculation.
