Vedclass · Answer

(D) The magnitude of a physical quantity $P$ remains constant regardless of the system of units used.If a physical quantity is expressed as $P = n_1 u_1 = n_2 u_2$, it implies that the numerical value $n$ is inversely proportional to the size of the unit $u$.Therefore, $n \propto \frac{1}{u}$.Thus, the correct relation is $n \propto \frac{1}{u}$.

Column-$I$	Column-$II$
