Question: A charge of +Q is fixed in space. A second charge of +q was first placed at a distance r1 away from +Q. Then it was moved along a straight line to a new position at a distance R away from its starting position. The final location of +q is at a distance r2 from +Q.
Part A: What is the charge in the potential energy of charge +q during this process?
I need help to find the charge in the potential energy of charge.
