A block is kept is kept over a horizontal platform, executing vertical SHM of angular frequency `omega`. Find maximum amplitude of oscillations, so that the block does not leave contact with the platform.

A coin is placed on a horizontal platform which undergoes vertical simple harmonic motion of angular frequency omega . The amplitude of oscillation is gradually increased. The coin will leave contact with the platform for the first time :
