Angular momentum is integral multiple of ( h /2 π) mvr =( nh /2 π) So momentum mv =( nh /2 π r )

Q. The momentum of an electron revolving in $n^{th}$ orbit is given by : (Symbols have their usual meanings)

$\frac{nh}{2 π r}$

$\frac{nh}{2 r}$

$\frac{nh}{2 π}$

$\frac{2 π r}{nh}$

Angular momentum is integral multiple of $\frac{h}{2 π} m v r = \frac{nh}{2 π}$
So momentum mv $= \frac{nh}{2 π r}$
