a student said "electric potential is always proportional to potential energy; why bother with the concept of potential at all? how would you respond?

1.The potential energy of a certain system of two charges increases as the charges are moved farther apart.What does this tell us about the sign of the charges?why?

2.Show that volt per meter is the same as newton per coulomb.
