The ratio of the dimensions of Planck’s constant and that of the moment of inertia is the dimensions of
Options
(a) frequency
(b) velocity
(c) angular momentum
(d) time
Correct Answer:
frequency
Explanation:
The dimensional formula for the Planck’s constant h= ML²T⁻¹
The dimension formula for the moment of Inertia I=ML²
The ratio between the Planck’s constant and moment of Inertia is,
h/I = ML²T⁻¹/ML²
= T⁻¹
= frequency
This is the frequency
