The magnitude of angular momentum, orbit radius and frequency of an electron in a hydrogen atom corresponding to the quantum number n are L, r and f respectively. Then, according to Bohr's theory of the hydrogen atom:

Options:(select one or more)

Answer:

A, B, C

Solution:

$f \propto n^{- 3}, r \propto n^{2}, L \propto n$ . Hence $f r L \propto n^{0}$ (A true); $L f \propto n^{- 2}$ (B true); $f r \propto n^{- 1}$ (C true); $L r \propto n^{3} \neq = n^{- 3}$ (D false).
