हिन्दीThe energy of the electron in the ground state of hydrogen atom is given by \( E_1 = -2.18 \times 10^{-18} \text{ J} \). What is the energy of the stationary state for \( n = 2 \)?
Correct answer · Option 2
\( -0.545 \times 10^{-18} \text{ J} \)
Explanation
Energy is given by \( E_n = -R_H (\frac{1}{n^2}) \). For \( n = 2 \), \( E_2 = -2.18 \times 10^{-18} (\frac{1}{2^2}) = -0.545 \times 10^{-18} \text{ J} \).
