Question

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 %`

Answer 1

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