Detailed Solution

The above statement is False.
A simple pendulum consists of a small metal ball called a bob which is suspended from the rigid support. This bob makes to and fro motion on small disturbances. Time taken for one oscillation to and fro is called the time period. The time period of the pendulum depends upon its length and gravity acceleration due to gravity. The length of the pendulum is the length of the thread from the rigid suspension to the centre of the bob. If the pendulum's thread is flexible, its length may be changed. However, the length of the string and the gravity acceleration used in the pendulum do not change. That's why the time period of the pendulum is constant.
The corrected statement would be that the time period of a simple pendulum is constant.
