Q. Angular momentum of an electron in the $n$ th orbit of hydrogen atom is given by
A) $\frac{nh}{2\pi}$
B) $nh$
C) $\frac{2\pi}{nh}$
D) $\frac{\pi}{2nh}$
Explanation
(a)
According to Bohr, an electron can move only in those orbits in which its angular momentum is a simple multiple of $\frac{h}{2\pi}$.
$i.e.,\ equal\ to\frac{nh}{2\pi}$(where, $n$ is an integer)
