Two particles execute SHM of the same time period along the same straight lines. They cross each other at the mean position while going in opposite directions. Their phase difference is

Two particles execute SHMs of the same amplitude and frequency along the same straight line. They cross one another when going in opposite direction. What is the phase difference between them when their displacements are half of their amplitudes ?

Two particles execute SHMs of the same amplitude and frequency along the same straight ling. They cross one another when going in opposite direction. What is th ephase difference between them when their displacements are half of their amplitudes ?

Two particles executes S.H.M. of the same amplitude and frequency along the same straight line. They pass one another when going in opposite directions, each time their displacement is root three by two times amplitude. The phase difference between them is

Two particles execute SHM of the same amplitude and frequency on parallel side by side. They cross each another when moving in opposite directions each time their displacement is half their amplitude What is the difference between them ?
