The bob of a 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 lscillation would.

A

(a) first decreade and then increase to the original value .

B

(b) first decreade and then increase to the original value .

C

(c ) increase towards a saturation value.

D

(d) remain unchanged.

Text Solution

Verified by Experts

The correct Answer is:
B
(b) Centre of mass of combination of liquid and hollow portion (at position l), first goes down (to l+Deltal) and when total water is drained out, centre of mass regain its original position (to l), `T=2pisqrtl/g`
:. `T' first increases and then decreases to original value.
