A rubber ball filled with water, having a small hole is used as the bob of a simple pendulum. The time period of such a pendulum
Options
- Ais a constant
- Bdecreases with time
- Cincreases with time
- Dfirst increases and then decreases, finally having same value as at the beginning
Correct answer
D. first increases and then decreases, finally having same value as at the beginning
Step-by-step solution
From T=2 L g The effective length increases due to this flow of water. Therefore, T increases. As the water flows out, the length decreases and becomes equal to the original length. Hence, the time period becomes equal to the value at the beginning.
