easy · MCQ · Q-937C95

According to Bohr's quantization condition, the angular momentum of an electron in the nn-th orbit is equal to:

  1. A.nπ/hn \pi / h
  2. B.nh/(2π)n h / (2\pi)Correct answer
  3. C.2πn/h2\pi n / h
  4. D.h/(nπ)h / (n \pi)

Solution

Bohr's postulate states that the orbital angular momentum LL of an electron is an integral multiple of h/(2π)h/(2\pi), i.e., L=mvr=nh2πL = mvr = \frac{nh}{2\pi}.
