A simple pendulum has a bob which is a hollow sphere full of sand and oscillates with certain period. If all that sand is drained out through a hole at its bottom, then its period
Options:
Answer:
C
Solution:
As the sand drains, the centre of mass of the bob first moves down and then rises back to the centre of the empty sphere.
The effective length first increases and then returns to its initial value, so the period first increases, then decreases and finally attains the value it had when the sphere was full of sand.
