The phase difference between displacement and acceleration of a particle in a simple harmonic motion is: (2020)
$ \frac{3\pi}{2} \text{ rad} $
$ \frac{\pi}{2} \text{ rad} $
Zero
$ \pi \text{ rad} $

Solution:

Displacement is given by $ y = A \sin(\omega t) $ and acceleration is $ a = -A\omega^2 \sin(\omega t) = A\omega^2 \sin(\omega t + \pi) $. Thus, the phase difference is $ \pi \text{ rad} $.
