Bohr Model: Orbits, Speed & Angular Momentum

The momentum of an electron revolving in $n$ th orbit is given by:

(Symbols have their usual meanings)

Show answer and solution

Answer: (a)

Angular momentum $L = pr = \frac{nh}{2\pi}$ .
$p = \frac{nh}{2\pi r}$
So the answer is (a) $\frac{nh}{2\pi r}$ .
