Solution
A pendulum is a weight suspended from a pivot so that it can swing freely.
When a pendulum is displaced sideways from its resting, equilibrium position, it is subject to a restoring force due to gravity that will accelerate it back toward the equilibrium position.
Time period of a pendulum is given by, where,
Hence, time period of a simple pendulum varies directly proportional as the square root of the length of the pendulum.
