The ratio of the dimensions of Planck constant and that of moment of inertia has the dimensions of

Options

A. frequency
B. velocity
C. time
D. angular momentum.

Answer

A

Explanation

`("Planck Constant")/("Moment of Inertia")=(ML^(2)T^(-1))/(ML^(2))=[M^(0)L^(0)T^(-1)]`
which are same as that of frequency.
So cannot choice is `(b)`.
