Question

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 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

and T1 > T2 Hence, time period first increases and then decreases to the original value.

Q. 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 oscillation would :

first increase and then decrease to the original value

first decrease and then increase to the original value

remain unchanged

increase towards a saturation value

and $T_{1} > T_{2}$
Hence, time period first increases and then decreases to the original value.
