If the radius of the electron orbit in the excited state of a hydrogen atom is $476.1 \ pm$, the energy of the electron in that excited state in $J$ is (Radius and energy of the electron in the first orbit of a hydrogen atom are $52.9 \ pm$ and $-2.18 \times 10^{-18} \ J$ respectively).

• A
  $-2.42 \times 10^{-18}$
• B
  $-19.62 \times 10^{-18}$
• C
  $-2.42 \times 10^{-19}$
• D
  $-6.05 \times 10^{-19}$
