Assertion: A pendulam is oscillating between points `A` , `B` and `C` . Acceleration of bob at points `A` or `C` is zero.

Reason: Velocity at these points is zero.

A

If 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, 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
At `A` and `C` , `v=0` . Therefore, radial acceleration `(v^(2))/(R)` is zero. But tangential acceleration `gsintheta` is non-zero.
