Question

charge is moved in an electric field of a fixed charge distribution from point A to another point B slowly. The work done by external agent in doing so is 100 J. What is the change in potential energy of the charge as it moves from A to B? What is the work done by the electric field of the charge distribution as the charge moves from A to B? let the charge be released from rest at point B what will be its kinetic energy when it crosses A?
