1. When a positive test charge +qo moves from point A to point B in an electric field, work WAB is done by the electric force. a. Write an equation that shows that work is equal to the electric potential energy (EPE) at A minus that at B. b. Write an equation that shows that the electric potential V at any given point is the electric potential energy of a small test charge at that point divided by the charge itself. c. Write an equation for the electric potential difference between two points A and B.
