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

Options:(select one or more)

Answer:

A, B, C, D

Solution:

$L \propto n, K \propto n^{- 2}, V \propto n^{- 1}, f \propto n^{- 3}$ . $K^{- 1} L f \propto n^{2 + 1 - 3} = n^{0} (A); K V f^{- 1} \propto n^{- 2 - 1 + 3} = n^{0} (B); L K^{- 1} V \propto n^{1 + 2 - 1} = n^{2} (C); K^{- 1} f \propto n^{2 - 3} =$ $1/ n (D)$ .
