angular momentum for p-electron

According to Bohr's model -

1. Force of attraction between the nucleus and an electron is equal to centripetal force.

2. $mvr=\frac{nh}{2\pi }$

n = principal quantum number.

3. Energy can be absorbed or emitted when electron transfers between the orbits  $E_{1}-E{_{2}}=h\nu$
The orbital angular momentum is given by $\sqrt{l(l+1)}\frac{h}{2\pi }$ where l is the azimuthal quantum number for p orbital, $l=1$

$\therefore$ orbital angular momentum = $\sqrt{(1)(1+1)} \frac{h}{2\pi }$

$= \sqrt{2} \frac{h}{2\pi } = \frac{h}{\sqrt{2}\pi }$
