Assertion : If a pendulum is suspended in a lift and lift accelerates upwards, then its time period will decrease.
Reason : Effective value of g will be `g_(e)=g+a`

A

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

B

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

C

If Assertion is true but Reason is false.

D

If Assertion is false but Reason is true.

Text Solution

Verified by Experts

The correct Answer is:
A
(a) T=2pidqrt((l)/(g_(e))`
Here, `g_(e)=g+a` , if the lift accelerates upwards.
