A : If speed of a particle is never zero...

A : If speed of a particle is never zero than it may have zero averag speed.
R : The average speed of a moving object in a closed path is zero.

A

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

B

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

C

If assertion is correct but reason is incorrect

D

If assertion is incorrect but reason is correct.

Text Solution

Verified by Experts

The correct Answer is:
d
If speed in never zero in an interval of time then the particle must have covered a certain distance , hencne its average speed cannot be zero. Similarly when the particle is moving in a circular path then distance covered by the particle in any interval is not zero hence the average speed cannot be zero.
