How do you determine kinetic energy?
Two equal point charges Q are separated by a distance of d. One of the charges released and moves away from the other due only to the electrical force between them. When the moving charge is a distance 3d away from the other charge, what is the kinetic energy?

Initial potential energy of each of the charge is
When one of them is at a distance 3d from the other,its potential energy is
Therefore,this change in potential energy i.e
