The angular momentum of the electron in a hydrogen atom is proportional to `n^(th)` power of r (radius of the orbit) where n is :-

Options

A. r
B. `r^2`
C. `sqrtr`
D. `1/r`

Answer

C

Explanation

Angular momentum (L) `=Iomega = mvr`
`mvr = (nh)/(2pi) , L prop n " but " r_n prop n^2`
`therefore n prop sqrtr therefore L prop sqrtr`
