Bohr Model: Orbits, Speed & Angular Momentum

According to Bohr's theory, the moment of momentum of an electron revolving in 44th orbit of hydrogen atom is:

Show answer and solution

Answer: (a)

  1. Moment of momentum =L=nh2π= L = \dfrac{nh}{2\pi}.
  2. For n=4n = 4: L=4h2π=2hπL = \dfrac{4h}{2\pi} = \dfrac{2h}{\pi}.
  3. So the answer is (a).
