the dimensional formula for planck's constant and angular momentum are

Options

A. `[ML^(3)T^(-2)]` and `[MLT^(-1)]`
B. `[ML^(2)T^(-1)] `and `[ML^(2)T^(-1)]`
C. `[ML^(2)T^(1)]` and` [ML^(3)T^(-2)]`
D. `[MLT^(-1)] `and` [MLT^(-2)]`

Answer

B

Explanation

`L = mvR = (nh)/(2 pi)`
:. `[L] = [h] = [mvR]`
