Vedclass · Answer

(B) Potential energy is defined as the work done against a conservative force,given by the formula $U = mgh$.The dimensions of mass $m$ are $[M^1]$.The dimensions of acceleration due to gravity $g$ are $[LT^{-2}]$.The dimensions of height $h$ are $[L^1]$.Therefore,the dimensional formula for potential energy is $[M^1] 	imes [LT^{-2}] 	imes [L^1] = [ML^2T^{-2}]$.
