Periodic time of a particle moving with simple harmonic motion is the time taken by the particle for A. Half oscillation B. Quarter oscillation C. Complete oscillation D. None of these

The correct answer is C. Complete oscillation.

The periodic time of a particle moving with simple harmonic motion is the time taken by the particle to complete one oscillation. One oscillation is defined as the particle moving from its equilibrium position to its maximum displacement, back to its equilibrium position, and then to its maximum displacement in the opposite direction.

Option A is incorrect because half an oscillation is not a complete oscillation.

Option B is incorrect because a quarter oscillation is not a complete oscillation.

Option D is incorrect because the periodic time is defined as the time taken for one complete oscillation.
