Assertion : The amplitude of an oscillation pendulum decreases gradually with time
Reason : The frequency of the pendulum decrease with time

A

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

B

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

C

If assertion is true but reason is false.

D

If the assertion and reason both are false

Text Solution

Verified by Experts

The correct Answer is:
