Answer to Question #129840 in Physics for Yanessa

Question

The work done by the electric force to move a charge q= 3x10^-7 C is 900 J. what is the potential difference that the charge moves through?

Answer 1

The work done by the electric force to move a charge

$$W=qV$$

The potential difference

$$V=\frac{W}{q}=\frac{900\:\rm J}{3\times 10^{-7}\:\rm C}=3\times 10^9\:\rm V=3\: GV$$
