If T is the time period of an oscillating pendulum, which one the following statements is not correct?

- The motion repeats after time T only once
- T is the least time after which motion repeats itself
- The motion repeats itself after nT, where n is a positive integer
- T remains the same only for small angular displacements

### Answer

A pendulum is a weight suspended from a pivot so that it can swing freely. The time for one complete cycle, a left swing and a right swing, is called the time period.

**The correct option is A.**
