A mass of 2.0 kg is put on a flat pan attached to a vertical spring fixed on the ground as shown the figure.The mass of the spring and the pan is negligible.When pressed slightly and released the mass executes a simple harmonic motion. The spring constant is `200 N//m.` What should be the minimum amplitude of the motion so that the mass gets detached from the pan `(Take g = 10m//s^2)

4.0 cm

8.0 cm

10.0 cm
