$A/B$

Vedclass · Answer

(A) According to the principle of homogeneity of dimensions,physical quantities can only be added or subtracted if they have the same dimensions. However,physical quantities can be multiplied or divided regardless of whether their dimensions are the same or different. Since $A$ and $B$ have different dimensions,the operations $A+B$ and $A-B$ are not physically meaningful. The operation $A/B$ is physically meaningful as it results in a new physical quantity with dimensions $[A]/[B]$.

If the dimensions of $A$ and $B$ are different,which of the following operations is physically meaningful?
