Vedclass · Answer

(D) The dimensional formula for energy per unit volume is $[M L^{-1} T^{-2}]$.The dimensional formula for angular momentum is $[M L^2 T^{-1}]$.Since these two quantities have different dimensions,they cannot be added or subtracted. Thus,Assertion $(A)$ is false.According to the principle of homogeneity of dimensions,only physical quantities having the same dimensions can be added or subtracted. Thus,Reason $(R)$ is true.Therefore,the correct option is $(d)$.

Assertion $(A)$: Energy per unit volume and angular momentum can be added dimensionally.
Reason $(R)$: Physical quantities having same dimensions can be added or subtracted.
