Per Bohr postulate (eqn 2.11), the angular momentum of an electron in the n-th allowed orbit is quantised as which expression?
Am_e v r = n²h
Bm_e v r = nλ
Cm_e v r = h ν
Dm_e v r = n h / (2π), with n = 1, 2, 3, …
Answer & Solution
Correct answer: D. m_e v r = n h / (2π), with n = 1, 2, 3, …
Per NCERT Bohr postulate iv (eqn 2.11), angular momentum is quantised: m_e v r = n h/(2π).
