The dimensions of Planck's constant are same as that of:
AAngular momentum
BLinear momentum
CEnergy
DPower
Answer & Solution
Correct answer: A. Angular momentum
Planck's constant $h$ has dimensions of energy $\times$ time: $[ML^2T^{-2}]\,[T]=[ML^2T^{-1}]$. Angular momentum also has dimensions $[ML^2T^{-1}]$.
