Bohr Model: Orbits, Speed & Angular Momentum

The frequency of revolution of the electron in Bohr's orbit varies with n, the principal quantum number as:

Show answer and solution

Answer: (c)

$f = \frac{v}{2\pi r}$ , $v \propto \frac{1}{n}$ , $r \propto n^2$ .
$f \propto \frac{1}{n^3}$
So the answer is (c) $\frac{1}{n^3}$ .
