Question

1) A 1C charge is pushed by an electric field, starting from rest, from a potential of 5V to a potential of 0V. Find its kinetic energy when it gets to the 0V region.

2) In the previous problem, find the velocity of the proton when it gets to the 0V region.

3) Two charged particles exert a 20 N force on each other. What force will they exert on each other if the distance between them is reduced to one-half its original distance?

Answer #1
