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:

Two particles $P$ and $Q$ describe simple harmonic motions of the same period, same amplitude, along the same line about the same equilibrium position $O$. When $P$ and $Q$ are on opposite sides of $O$ at the same distance from $O$, they have the same speed of $1.2 \mathrm{m} {\mathrm{s}}^{-1}$ in the same direction. When their displacements are the same, they have the same speed of $1.6 \mathrm{m} {\mathrm{s}}^{-1}$ in opposite directions. The maximum velocity in $\mathrm{m} {\mathrm{s}}^{-1}$ of either particle is
