MCQ

$Assertion$ : 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 $Q$.

A
If both Assertion and Reason are correct and the Reason is a correct explanation of the Assertion.
B
If both Assertion and Reason are correct but Reason is not a correct explanation of the Assertion.
C
If the Assertion is incorrect but the Reason is correct.
✓
If the Assertion is correct but Reason is incorrect.

✓

Answer

Correct option: D.

If the Assertion is correct but Reason is incorrect.

d
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.
