Question

The magnitude of any physical quantity

• A. depends on the method of measurement.
• B. does not depends on the method of measurement.
• C. is more in SI system than in CGS system.
• D. directly proportional to the fundamental units of mass, length and time.

Answer 1

The correct option is B does not depends on the method of measurement.

Magnitude of any physical quantity $=$ Numerical value.
Magnitude of a physical quantity is always constant.
It is independent of the type of unit.
$\text{Numerical Value}\propto \frac{1}{\text{Unit}}$
$n_1{u}_1=n_2{u}_2=\text{Constant}$
