Question

A coin is placed on the horizontal plate. Plate performs S.H.M. vertically with angular frequency ' ω ′ . The amplitude (A) of oscillations is gradually increased. The coin will lose contact with plate for the first time when amplitude is ( g = acceleration due to gravity )

TestHub · Accepted Answer

(D) The coin will lose contact with the plate when its acceleration in downward direction just exceeds acceleration due to gravity. ∴ ω 2 x = g ∴ x = ω 2 g ​ ​
