Question

10. A hollow brass bob is used to set up a simple pendulum, such that its time period is T How is value
of T affected when.
1/2of the brass is filled with mercury? give reason
2​

Answer 1

Answer:

Time Period will Increase

Explanation:

Time period for pendulum =$2\pi \sqrt{\frac{L}{g}}$  as u put mercury in the bob the effective length increase because the centre of mass of bob will go down so the distance between the point of suspension and the center of mass will increase. Therefore, the time period will increase, as it is directly proportional

to L.

Thank You.

Answer 2

Answer:

THE TIME PERIOD REMAINS THE SAME

Explanation:

The time period of the pendulum is = 2 pie*$\sqrt{l/g}$.

So the mass does not effect it.

Hope it helps
