Out of the following pairs which one does not have identical dimensions ?

Options

A. Moment of inertia and moment of a force
B. Work and torque
C. Angular momentum and Planck's constant
D. Impulse and momentum

Answer

A

Explanation

Moment of inertia `(I)= m^(2):. [I]= [ML^(2)]`
Moment of force `(bartau)= barr xx bar F`
`:. [tau]= [r][F]= [L][MLT^(-2)]` or `[tau]= [ML^(2)T^(-2)]`
Moment of inertia and moment of a force do not have identical dimensions
