The ratio of the dimensions of Planck’s constant of that of moment of inertia is the dimension of
Options
- AAngular momentum
- BVelocity
- CFrequency
- DTime
Correct answer
C. Frequency
Step-by-step solution
The dimensions of Planck’s constant, h = E v = M L 2 T - 2 M 0 L 0 T - 1 = M L 2 T - 1 And that moment of inertia, l = M R 2 = M L 2 = M L 2 T 0 ∴ h l = M L 2 T - 1 M L 2 T 0 = T - 1 = v
