Question

The time period of a particle in simple harmonic motion is equal to the time between consecutive appearances of the particle at a particular point in its motion. Thi point is
(a) the mean position
(b) an extreme position
(c) between the mean position and the positive extreme
(d) between the mean position and the negative extreme.

Answer 1

Answer ⇒ Option (a). Extreme Position.

Explanation ⇒ The time period of a particle in simple harmonic motion is equal to the time between consecutive appearances of the particle at a particular point in its motion. That Point will be the extreme Position.

At the extreme position the particle is in the same phase at consecutive appearance. This means, the consecutive appearance of the particle is always is in the same phase.

Thus, Option(b). is correct.

In all other Options, Consecutive appearance of the particle is not always in the same phase.

Hope it helps.
