Ratio of unit of Planck's constant and moment of inertia will give which physical quantity ?

Options

A. time
B. frequency
C. angular momentum
D. velocity

Explanation

Planck.s constant (h)
`E=hf`
`h=(E)/(f)=(M^(1)L^(2)T^(-2))/(T^(-1))=M^(1)L^(2)T^(-1)`
Moment of inertia,
`1=Mr^(2)`
`=kg m^(2)`
`=M^(1)L^(2)T^(0)`
`:.` Ratio `=(h)/(I)=(M^(1)L^(2)T^(-1))/(M^(1)L^(2)T^(0))`
`=M^(0)L^(0)T^(-1)` Dimension of frequency
