Answer:

Correct Answer: 4. (c)

Solution:

The ground state energy of $H$ -atom is $+ 13.6 eV$ .

For second excited state, $n = 2 + 1 = 3$

$\begin{matrix} ∴ E_{3} ({He}^{+}) = - 13.6 \times \frac{Z^{2}}{n^{2}} eV [∵ for {He}^{+}, Z = 2] = - 13.6 \times \frac{2^{2}}{3^{2}} eV = - 6.04 eV \end{matrix}$
