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 $n \propto \frac{1}{u}$.

$A$ physical quantity is measured and its value is found to be $nu$, where $n$ is the numerical value and $u$ is the unit. Then which of the following relations is true?
