Given below are two statements: one is labelled as Assertion A and the other is labelled as Reason R:
Assertion A: Dimensional constants are the quantities whose magnitudes are constant.
Reason R: Dimensional constants are always unitless.
In the light of the above statements, choose the correct answer from the options given below:
A is true but R is false
A is false but R is true
Both A and R are true and R is the correct explanation of A
Both A and R are true but R is NOT the correct explanation of A.
Dimensional constants are the quantities whose value are constant and they possess dimensions. For example, velocity of light in vacuum, universal gravitational constant, Boltzmann constant, Planck’s constant etc.
