A simple pendulum has a bob which is a hollow sphere completely filled with water and oscillates with a certain period. If the water drains out slowly through a hole at the bottom of the bob, then during the draining its period
Options:
Answer:
A
Solution:
As the water leaves, the centre of mass of the bob-water system first falls (lengthening the pendulum) and then rises back to the centre of the empty sphere.
The period first increases and then decreases, returning to its initial value.
