A coin is placed on the horizontal plate. Plate performs S.H.M. vertically with angular frequency ' ^ . 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 )

Options

  1. Ag ²
  2. Bzero
  3. C² ~g
  4. DA 2

Correct answer

A. g ²

Step-by-step solution

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