Energy of the Electron & Energy Levels

If the electron in a hydrogen atom moves from ground state orbit to 5th orbit, then the potential energy of the electron

Show answer and solution

Answer: (a)

$PE = -\frac{ke^2}{r}$ with $r \propto n^2$ .
From $n = 1$ to $n = 5$ , $r$ grows 25 times, so PE becomes less negative ( $-27.2\text{ eV} \to -1.09\text{ eV}$ ).
So the answer is (a) is increased.
