CBSE · Class 11 · Physics · OscillationsWhat is the time period of a simple pendulum inside a freely falling elevator?
Step-by-Step Solution
In a freely falling elevator, effective acceleration due to gravity $g_{\text{eff}} = g - g = 0$. Since $T = 2\pi \sqrt{\frac{l}{g_{\text{eff}}}}$, division by zero yields $T = \infty$ (infinite).
