A girl is swinging a swing in the sitting position. What will be the effect on the time period of the swing if she stand up?

A

increase

B

decrease

C

remain same

D

increase if the child is tall and decrease if the child is short

Text Solution

Verified by Experts

The correct Answer is:
B
When child stands up, moment of inertia decreases, hence angular speed `omega` increases and as a result periodic time decreases.
