Vedclass · Answer

(A) Torque $(		au)$ is defined as the product of force and the perpendicular distance from the axis of rotation.Mathematically,$	au = 	ext{Force} 	imes 	ext{Distance}$.The dimensional formula for force is $[M L T^{-2}]$.The dimensional formula for distance is $[L]$.Therefore,the dimensional formula for torque is $[M L T^{-2}] 	imes [L] = [M L^2 T^{-2}]$.Thus,the correct option is $A$.
