Physics - SHM Question with Solution | TestHub

Two particles are executing simple harmonic motion of the same amplitude A and frequency $\omega$ along the $x$-axis. Their mean position is separated by distance $X_0\left(X_0>A\right)$. If the maximum separation between them is $\left({\mathrm{X}}_0+\mathrm{A}\right)$, the phase difference between their motion is :-
