The ratio of the dimension of planck constant and that of moment of inertia is the dimension of ……….

Options

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

Answer

B

Explanation

`("Panck's constant")/("Moment of inertia")=(h)/(M.I)=((E )/(v))/(mr^(2))`
`"Dimension of "=(h)/(M.I)=((ML^(2)T^(-2))/(T^(-1)))/(ML^(2))=T^(-1)`
