Question

A stationary protonis moved from front A, where the potential is 450.0v, to point B, where the potential is 125V. (a) what is the potential difference between point A and point B? (b) How much work is done by the electric force?

Answer 1

(a)

$\Delta\phi=450-125=325\ (V)$ . Answer

(b)

$W=q\Delta \phi=1.6\cdot10^{-19}\cdot325=520\cdot10^{-19}\ (J)$ . Answer
