The angular speed of the electron in the `n^(th)` Bohr orbit of the hydrogen atom is proportional to

A

directly proportional to n

B

inversely proportional to `sqrtn`

C

inversely proportional to `n^(2)`

D

inversely proportional to `n^(3)`

Text Solution

Verified by Experts

The correct Answer is:
D
`omega=(v)/(r )`. Further `vprop(1)/(n) and r prop n^(2)`,
hence `omega prop (1//n^(3))`.
