Physics
##### ASSERTION

Angle and angular displacement are dimensionless quantities.

##### REASON

Angle is equal to arc length divided by radius.

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
