Which from following equations is used to express the angular momentum of an electron in a stationary state?

Which from following equations is used to express the angular momentum of an electron in a stationary state?
  1. $\mathrm{mvr}=\frac{\mathrm{nh}}{2 \pi}$
  2. $\mathrm{mvr}=\frac{2 \pi}{\mathrm{nh}}$
  3. $\mathrm{r}=\frac{\mathrm{mvh}}{\mathrm{n} 2 \pi}$
  4. $\mathrm{mv}=\frac{2 \pi \mathrm{r}}{\mathrm{nh}}$

Solution

$\mathrm{mvr}=\frac{\mathrm{nh}}{2 \pi}$ is use to express t e angular momentum of an electron in a stationary state.
