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 `sqrt(n)`

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 `rpropn^2`. Hence `omegaprop(1//n^3)`
