The horizontal platform shown between the springs and the springs themselves have no mass. If the mass M is slightly displaced vertically, the mass exhibits simple harmonu-;ls(li0tp n6iq xq)ic oscillation. Assume that the horizontal platform does not rotate during the oscillations.What is the period of the oscillation?
