MCQ
A particle is performing S.H.M. starting from extreme position. Graphical representation shows that, between displacement and acceleration, there is a phase difference of
- A$0 rad$
- B$\frac{\pi}{4} rad$
- C$\frac{\pi}{2} rad$
- ✓$\pi rad$
✓
Answer
Correct option: D.
$\pi rad$
(d) : Acceleration of a particle performing S.H.M. is $a=-\omega^2 x$ or $a \propto-x$
$\therefore \quad$ There is a phase difference of $\pi$ between displacement and acceleration.
$\therefore \quad$ There is a phase difference of $\pi$ between displacement and acceleration.
