If P, Q, R are physical quantities, having different dimensions, which of the following combinations can never be a meaningful quantity ?

A

`((P-Q))/(R)`

B

`PQ-R`

C

`(PQ)/(R)`

D

`((PR-Q^(2)))/(R)`

Text Solution

Verified by Experts

Quantities with different dimensions can never be added or substracted in each other. Hence (A) and (E) are not meaningful
