Vedclass · Answer

(A) Calorie is a unit of heat,which is a form of energy.Since energy is defined as the capacity to do work,its dimensional formula is the same as that of work.Work = Force $	imes$ Displacement.Dimensional formula of Force = $[M L T^{-2}]$.Dimensional formula of Displacement = $[L]$.Therefore,the dimensional formula of energy (and thus calorie) = $[M L T^{-2}] 	imes [L] = [M L^2 T^{-2}]$.
