A simple pendulum has some time period `T`. What will be the percentage change in its time period if its amplitude is decreased by `5%`

A

`6 %`

B

`3 %`

C

`1.5 %`

D

`0 %`

Text Solution

Verified by Experts

The correct Answer is:
D
`T = 2pisqrt((l)/(g))`, As it does not depend on amplitude
`:. %` change in time period is `0%` Hence option `(D)` is correct.
