I have come across the following paragraph from my book
"The gravitational force is always attractive .Whereas the electric force is attractive or repulsive acording to whether q0 is negative or positive.Each of the above forces is conservative,so a potential energy is associated with each of them.This potential energy must of course take the same form for both cases."
I want to know which form is it talking about?And why both cases would take the same form?
