Question:
a. Charge q1 is distance r from a positive point charge Q. Charge q2 = q1/3 is distance 2r from Q. What is the ratio U1/U2 of their potential energies due to their interactions with Q?
b. Charge q1 is distance s from the negative plate of a parallel-plate capacitor. Charge q2 = q1/3 is distance 2s from the negative plate. What is the ratio U1/U2 of their potential energies?
