A simple pendulum hanging from the ceiling of a stationary lift has a time period T 1 . When the lift moves downward with constant velocity, the time period is T2, then

A

`t_(2)` is infinity

B

`t_(2)gt t_(1)`

C

`t_(2)lt t_(1)`

D

`t_(2) =t_(1)`

Text Solution

Verified by Experts

The correct Answer is:
D
The lift is moving with constant velocity, so there will be bo change in the acceleration. Hence, time period will remain same.
