If two SHMs of different amplitudes are added together, the resultant SHM will be a maximum if the phase difference between them is:

Two particles execute simple harmonic motions of same amplitude and frequency along the same straight line. They cross one another when going opposite directions. The phase difference between them when their displacements are one half of their amplitudes is then:
