Which of the following equations gives angular momentum of an electron in a stationary orbit?

Which of the following equations gives angular momentum of an electron in a stationary orbit?
  1. $\mathrm{mvr}=\frac{2 \pi}{\mathrm{~h}} \times \mathrm{n}$
  2. $\mathrm{m} v \mathrm{r}=\frac{\mathrm{nh}}{2 \pi}$
  3. $\mathrm{mvh}=\mathrm{n} \times \frac{\mathrm{r}}{2 \pi}$
  4. $\mathrm{mv}=\left(\frac{\mathrm{h} \times \mathrm{r}}{2 \pi}\right) \mathrm{n}$

Solution

The equation that gives the angular momentum of an electron in a stationary orbit, according to Bohr's model of the atom, is: $m v r=\frac{n h}{2 \pi}$
