The bob of simple pendulum is a spherical hollow ball filled with water. A plugged hole near the bottom of the oscillating bob gets suddenly unplugged. During observation, till water is coming out, the time period of oscillation would.

A

first increase and then decrease to the original value

B

first decrease and then increase to the original value

C

remain unchanged

D

increase towards a saturation value

Text Solution

Verified by Experts

The correct Answer is:
A
The expression of time period of a simple pendulum
`T = 2pisqrt((l_(eff))/(g_(eff)))`
Where `l_(eff)` is the distance between point of suspension and centre of gravity of bob. As the hole is suddenly unplaugged, `l_(eff)` first increases then decrease because of shifting of CM due to which the time period first increases and then decreases to the original value.

Assertion : The bob of a simple pendulum is a ball full of water, if a fine hole is made in the bottom of the ball, the time period first increases and then decreases. Reason : As water flows out of the bob the weight of bob decreases.

A hollow sphere is taken as bob of a simple pendulum. This hollow sphere is filled with fine sand. There is a small hole at the bottom of this sphere through which the fine sand leaks out. How does the time period of this simple pendulum alter? Discuss.

Suppose the bob in a simple pendulum is a hollow sphere with a small hole at the bottom. The sphere is filled with water and is made to oscillate. What happens to the period ?

A hollow sphere is filled with water. It is hung by a long thread. As the water flows out of a hole at the bottom, the period of oscillation will

The bob of a simple pendulum is displaced from its equilibrium position 'O' to a position 'Q' which is at a height 'h' above 'O' and the bob is then released. Assuming the mass of the bob to be 'm' and time period of oscillation to be 2.0s , the tension in the string when the bob passes through 'O' is
