Assertion : If a pendulum is suspended in a lift and lift is falling freely , then its time period becomes infinite .
Reason : Free falling body has acceleration equal to acceleration due to gravity .

A

Both assertion and reason are true and reason explains assertion correctly.

B

Both assertion and reason are true and reason does not explain assertion correctly.

C

Both assertion and reason are false.

D

Assertion is true but reason is false.

Text Solution

Verified by Experts

The correct Answer is:
B
Assertion: When a pendulum falls freely its accelerationn is zero.
`thereforeT=2pisqrt((l)/(0))="infinite"`
Reason: For a free falling body acceleration is equal to `sqrt(g)`.
