Assertion: The instantaneous velocity do...

Assertion: The instantaneous velocity does not depend on instantaneous position vector.
Reason: The instantaneous velocity and average velocity of a particle are always same.

A

If both assertion and reason are true and reason is the correct explanation of assertion.

B

If both assertion and reason are true but reason is not the correct explanation of assertion.

C

If assertion is true but reason is false.

D

If assersion is false but reason is true.

Text Solution

Verified by Experts

The correct Answer is:
C
As `vec v = (d vec s)/(dt)`, hence statement `1` is correct.
Instantaneous velocity is same always to average velocity if the particle is moving with constant velocity.
