Which one of the following is a dimensional constant?

A

Refractive index

B

Dielectric constant

C

Relative density

D

Gravitational constant

Text Solution

Verified by Experts

The correct Answer is:
d
Refractive index, Dielectric constant and relative density are the ratios of the magnitudes of the same physical quantity. They have no units and dimensions. But gravitational constant G has a constant value and it has dimensions. Hence it is a dimensional constant.
