MP Board · Class 11 · Physics · OscillationsThe time period of a simple pendulum in a freely falling lift is:
Step-by-Step Solution
In a freely falling lift, the effective acceleration due to gravity $g_{eff} = g - g = 0$. Since $T = 2\pi \sqrt{\frac{L}{g_{eff}}}$, as $g_{eff} \to 0$, $T \to \infty$.
