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:
Text Solution
Verified by ExpertsThe correct answer is:
A
T < T 1 > T 2
T = 2 π 
T 1 = 2 π 
T2 = 2 π 
and T 1 > T 2
Hence, time period first increases and then decreases to the original value.
