STANDARD Physics Simple Harmonic Motion MCQ Question

In simple harmonic motion (SHM), the displacement $x(t)$ and velocity $v(t)$ are related by a phase difference of $\frac{\pi}{2}$ radians, meaning that the velocity reaches its maximum value when the displacement is at zero. Thus, the phase difference between velocity and displacement is $\frac{\pi}{2}$, making option (B) the correct choice. Options (A) and (D) are incorrect because a phase difference of 0 would imply that velocity and displacement are in sync, and a phase difference of $2\pi$ indicates a complete cycle, which does not apply to their relationship in SHM.
