ASSERTION

Angle and angular displacement are dimensionless quantities.

REASON

Angle is equal to arc length divided by radius.


ANSWER

Both Assertion and Reason are correct but Reason is not the correct explanation for Assertion


SOLUTION
Angle or angular displacement $$\displaystyle = \frac{Arc\,Lenght}{Radius} = \frac{[L]}{[L]}$$. It is a dimensionless quantity
