• (A) The periodic time of a particle moving with simple harmonic motion is the time taken by a particle for one complete oscillation.
• (B) The periodic time of a particle moving with simple harmonic motion is directly proportional to its angular velocity.
• (C) The velocity of a particle moving with simple harmonic motion is zero at the mean position.
• (D) The acceleration of the particle moving with simple harmonic motion is maximum at the mean position.
