AP EAMCET · PHYSICS · Oscillations
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 remain unchanged
- B increase towards a saturation value
- C first increase and then decrease to the original value.
- D first decrease and then increase to the original value.
Answer & Solution
Correct Answer
(C) first increase and then decrease to the original value.
Step-by-step Solution
Detailed explanation
The time period of the simple pendulum is, T=2πlg Here, l is the effective length of the pendulum up to centre of mass. When the hole at bottom of the hollow sphere (bob) filled with water is unplugged, the water will drain from the bob due to which the centre of…
