Two simple harmonic motions with the same frequency act on a particle at right angles i.e., along X-axis and Y-axis. If the two amplitudes are equal and the phase difference is π/2, the resultant motion will be. along X-axis and Y-axis. If the two amplitudes are equal and the phase difference is π/2 the resultant motion will be.
