A hydrogen atom in ground state absorbs $\mathrm{10.2 }\mathrm{e}\mathrm{V}$ of energy. The orbital angular momentum of the electron is increased by

• Correct answer
  A

  $1.05\times 10^{–34}\mathrm{J}\mathrm{s}$
• B

  $2.11\times 10^{–34}\mathrm{J}\mathrm{s}$
• C

  $3.16\times 10^{–34}\mathrm{J}\mathrm{s}$
• D

  $4.22\times 10^{–34}\mathrm{J}\mathrm{s}$

Hence, the correct answer is option: 'A'.
