Q. The phase difference between displacement and acceleration of a particle in a simple harmonic motion is :
A) $\frac{3\pi}{2}$ rad
B) $\frac{\pi}{2}$ rad
C) zero
D) $\pi$ rad
Explanation
[Solution] $a = -\omega^2x$, so acceleration is opposite to displacement: phase difference $\pi$ rad. Answer (4).
