GP Motion Force

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

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


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.
