A horizontal platform with an object placed on it is excuting SHM in the vertical direction.  The amplitude of oscillation is 2.5 cm.

What must be the least period of these oscillations so that the object is not detached from the platform?  Take g = 10 ms-2.

Expert Answer:

The object will not get detached from the platform, if the angular frequency  is such that during the downward motion the maximum acceleration equals the acceleration due to gravity, i.e.,
