ncno ;-g sa)e:rings of spring constant k are connected as shown to a mass
en nc;:g as-o)M in equilibrium. 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 harmonic oscillation. Assume that the horizontal platform does not rotate during the oscillations.What is the period of the oscillation?
