A second's pendulum has a hollow spherical bob of mass `25xx10^(-3)kg`. It is replaced by another solid bob of same radius but of mass `50xx10^(-3)kg`. Then the new time period will be

A

6s

B

4s

C

3s

D

2s

Text Solution

Verified by Experts

The correct Answer is:
D
Time period is independent of mass of the pendulum `therefore T = 2s`.
