Question

A single pendulum hanging vertically in an elevator has a time period 𝑇0 when the elevator is stationary. If the elevator moves upward with an acceleration of 𝑎 = 0.2𝑔, the time period of oscillations is 𝑇1. Here 𝑔 is the acceleration due to gravity. The ratio$\frac{𝑇_0}{ 𝑇_1}$ is (rounded off to two decimal places).

Answer 1

The correct answer is: 1.09 to 1.11 (approx)
