Vedclass · Answer

(B) The dimensions of the given physical quantities are as follows:$A$. Angular momentum $(L = mvr)$ and Planck's constant $(h = E/f)$ both have dimensions $[M L^2 T^{-1}]$.$B$. Moment of inertia $(I = mr^2)$ has dimensions $[M L^2]$. Moment of a force (Torque,$	au = r 	imes F$) has dimensions $[M L^2 T^{-2}]$. These are not identical.$C$. Work $(W = F \cdot d)$ and torque $(	au = r 	imes F)$ both have dimensions $[M L^2 T^{-2}]$.$D$. Impulse $(J = F \Delta t)$ and momentum $(p = mv)$ both have dimensions $[M L T^{-1}]$.Therefore,the pair that does not have identical dimensions is Moment of inertia and moment of a force.

Out of the following,the only pair that does not have identical dimensions is
