An electron has 5.7 x 10-18 J of electric potential energy at position A from a positive point charge. If it is moved to position B where it has 7.7 X 10-18 J of potential energy, what is the voltage between positions A and B? Would it have to be moved towards or away from the positive point charge to gain this energy?
