प्रश्न
A simple pendulum is hollow from within and its time period is T. How is the time period of pendulum affected when :
- 1/4 of bob is filled with mercury
- 3/4 of bob is filled with mercury
- The bob is completely filled with mercury?
उत्तर
We know that the time period of a simple pendulum is independent of its mass. So in all the above said cases, the time period of the simple pendulum remains the same.
