Which one of the following physical quantities has the same dimensions as that of Planck’s constant h?

Linear momentum
Angular momentum
Force
Potential energy

Correct Answer: Angular momentum

Explanation:

In S.I. System unit of angular momentum is "joule.Second".

SI unit of Planck's constant is joule-seconds(j-s).
