Given :  Different  variables  

To Find : Which of the following is not a dimensionless variable  

(a) Refractive Index

(b) Relative density

(c) Angular displacement

(d) Angular velocity​

Solution:

Refractive Index is  relative speed at which light moves through a material with respect to  speed in vacuum

Hence Refractive Index is Dimensionless

Relative density is relative density with respect to density of water

Hence Relative density is  Dimensionless  

Angular displacement is ratio of the length of the arc to the radius of the circle

Hence Angular displacement   is  Dimensionless  

Angular velocity​ is measure of rotation rate,

Hence its dimension is  T⁻¹

Hence Angular velocity​  is  not a dimensionless variable
