Energy of the Electron & Energy Levels

In the third orbit of hydrogen atom the energy of an electron ' $E$ '. In the fifth orbit of helium $(Z = 2)$ the energy of an electron will be

Show answer and solution

Answer: (b)

$E_n \propto \frac{Z^2}{n^2}$ .
$\frac{E_{He,5}}{E_{H,3}} = \frac{4/25}{1/9} = \frac{36}{25}$
So the answer is (b) $\frac{36E}{25}$ .
