Question

In case of a simple pendulum, time period versus length is depicted by

Answer 1

The correct depiction is a curve where the time period increases as the square root of the length (i.e., $T \propto \sqrt{L}$).

Answer 2

Core Explanation:

For a simple pendulum, the time period is given by

$$T = 2\pi\sqrt{\frac{L}{g}}$$

This shows that $T$ is proportional to $\sqrt{L}$. Therefore, the graph of time period versus length is a square-root curve.
