Electric Field Potential AP C

A solid sphere of radius R�has charge +Q distributed uniformly throughout its volume. The sphere and five labeled points are shown in the figure. Which of the following indicates which points would have values for the electric potential and electric field due to the sphere that are identical to the values of the electric potential and electric field if the sphere was a point particle with charge +Q ?

• Point A only

• Point B only

• Points A and B

• Points C, D, E

• All points would have the same potential and Electric field

Isolated spheres 1 and 2 both carry positive charge q, but sphere 2 has more mass than sphere 1. The objects are released from rest when they are a distance d apart and accelerate away from each other. Let U be the electric potential energy of the system of two spheres, and K1 and K2 be the kinetic energies of sphere 1 and sphere 2, respectively. Which of the following pairs of energy bar charts could represent the distribution of the energies in the system when the spheres are first released and the distribution of energies when the spheres are a very large distance away from each other?
