A girl is swinging on a swing in the sitting position. How will the period of swing be affected if she stands up?

The period will now be shorter

The period will now be longer

The period will remain unchanged

The period may become longer or shorter depending upon the height of the girl

Text Solution

Verified by Experts

The correct Answer is:

The effective value of 1 will decrease. Therefore, the time period will be shorter.
