Dimensional formula for torque is:

A

ML2T2ML^2T^{-2}

B

ML1T2ML^{-1}T^{-2}

C

ML2T3ML^2T^{-3}

D

MLT2MLT^{-2}

Step-by-Step Solution

Torque (ττ), also known as the moment of force, is defined as the product of force and the perpendicular distance from the axis of rotation . Based on the sources, force has the dimensional formula [MLT2][MLT^{-2}] and distance has the dimension [L][L] . Therefore, the dimensions of torque are calculated as [MLT2]×[L]=[ML2T2][MLT^{-2}] \times [L] = [ML^2T^{-2}] . It is noteworthy that torque shares the same dimensions as work and energy .
