Assertion : We know the relation a = v. ...

Assertion : We know the relation `a = v. (dv)/ds` . Therefore, if velocity of a particle is zero, then acceleration is also zero.
Reason : In the above equation, a is the instantaneous acceleration.

A

If the both Assertion and Reason are true and the Reason is correct explanation of the Assertion.

B

If both Assertion and Reason are true but Reason is not the correct explanation of Assertion.

C

If Assertion is true, but the Reason is false.

D

If Assertion is false but the Reason is true.

Text Solution

Verified by Experts

The correct Answer is:
D
It is not necessary that if `v=0` then acceleration is
also zero. If a particle is thrown upwards, then at
highest point `v=0`but `!=0`
