Vedclass · Answer

(B) The potential energy $(PE)$ of an electron at a distance $r$ from the nucleus of charge $Ze$ is given by the electrostatic potential energy formula:$PE = \frac{k_e q_1 q_2}{r}$Here,$q_1 = Ze$ (charge of the nucleus) and $q_2 = -e$ (charge of the electron).Thus,$PE = \frac{k_e (Ze)(-e)}{r} = -\frac{k_e Z e^2}{r}$.In Gaussian units where $k_e = 1$,the expression simplifies to $PE = -\frac{Z e^2}{r}$.
