Question

A particle is executing simple harmonic motion with an amplitude A and time period T. The displacement of the particle after 2T periodfrom its intial position is

Answer 1

A time period (denoted by 'T' ) is the time needed for one complete cycle of vibration to pass in a given point. And,amplitude is the maximum displacement of a particle on either side.

Hence for a wave the amplitude remains same. So the answer is A.
