Moving a point charge of 3.2 x 10^-19 C between points A and B in an electric field requires 4.8 x 10^-19 J of energy. What is the potential difference between these two points?

Answer 1

It is simple problem based on electrical energy for a charge

E = q * V

q = charge

E = energy

V = potential difference

So

V = E/q = 1.5 volt
