The horizontal platform shown between the springs and the spring6qsbhbx+cja ku)*;2 os 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?
