If 20 J of work has to be done to move an electric charge of 4 C from a point, where potential is 10 V to another point, where potential is V , find the value of V .

Question

If 20 J of work has to be done to move an electric charge of 4 C from a point, where potential is 10 V to another point, where potential is V , find the value of V ., 2 V, 70 V, 5 V, 15 V
