Energy of the Electron & Energy Levels

If 'E' and 'L' denote the magnitude of total energy and angular momentum of revolving electron in nthn^{th} Bohr orbit then

Show answer and solution

Answer: (c)

  1. Bohr model: E∝1n2E \propto \frac{1}{n^2} and L=nh2π∝nL = \frac{nh}{2\pi} \propto n.
  2. So E∝1L2=L−2E \propto \frac{1}{L^2} = L^{-2}
  3. So the answer is (c) E∝L−2E \propto L^{-2}.
