STANDARD Physics Simple Harmonic Motion MCQ Question
A simple pendulum suspended from roof of a lift oscillates with frequency v when the lift is at rest. If the lift falls freely under gravity, its frequency of oscillation becomes
zero
v
2v
infinite
Correct Answer
Detailed Explanation
When the lift is at rest, the frequency of oscillation of a simple pendulum is v = 1/(2π)√(g/L). When the lift falls freely, the effective acceleration due to gravity becomes zero, making the frequency zero.
