The dimension of Planck's constant are the same as that of

A

charge

B

work

C

force

D

Angular momentum

Text Solution

Verified by Experts

The correct Answer is:
D
Energy of a photon `E=hupsilon`
where h is the planck's constant and `upsilon` is the frequency.
`therefore[h]=([E])/([upsilon])=([ML^(2)T^(-2)])/([T^(-1)])=[ML^(2)T^(-1)]`
Angular momentum=moment of inertia `xx` angular velocity
[Angular momentum]`=[ML^(2)][T^(1)]=[ML^(2)T^(-1)]`
