Physics

Assertion: The dimensional formula for relative velocity is same as that of the change in velocity.
Reason: 
Relative velocity of P w.r.t. Q is the ratio of velocity of P and that of Q.


ANSWER

Assertion is true but reason is false


SOLUTION

Relative velocity which is vector subtraction of two velocities will also be a vector of the form of velocity so, its dimensional formula will remain unchanged. Relative velocity is measured not by calculating ratio but by calculating difference.
