A simple pendulum is placed inside a lift, which is moving with a uniform acceleration. If the time periods of the pendulum while the lift is moving upwards and downwards are in the ratio \(1: 2\), then the acceleration of the lift is (Acceleration due to gravity, \(g=10 \mathrm{~ms}^{-2}\) )
- A \(6 \mathrm{~ms}^{-2}\)
- B \(0 \mathrm{~ms}^{-2}\)
- C \(3 \mathrm{~ms}^{-2}\)
- D \(2 \mathrm{~ms}^{-2}\)
Answer & Solution
Correct Answer
(A) \(6 \mathrm{~ms}^{-2}\)
Step-by-step Solution
Detailed explanation
Given, time period of the pendulum while the lift is moving upwards and downward are in the ratio, \(T_1: T_2=1: 2\) Acceleration due to gravity, \(g=10 \mathrm{~m} / \mathrm{s}^2\) We know that, If the lift is moving upward, then total time-period,…
