## It takes 50 J of  energy to move a 5 C charge from point a to point b, the potential difference between point a and b is

1. It takes 50 J of  energy to move a 5 C charge from point a to point b, the potential difference between point a and b is:

1. 250 V
2. 10 V
3. 5 V
4. 500 V

Explanation: Mathematically, V = W/Q = 50 J/5C = 10 V
