Energy of the Electron & Energy Levels

If $13.6\text{ eV}$ energy is required to ionize the hydrogen atom, then the energy required to remove an electron from $n = 2$ is

Show answer and solution

Answer: (c)

Energy to remove electron from level $n$ $= \frac{13.6}{n^2}$ eV.
$n = 2$ : $\frac{13.6}{4} = 3.4$ eV
So the answer is (c) $3.4$ eV.
