A mass of `2.0 kg` is put on a flat pan attached to a vertical spring fixed on the ground as shown in the figure. The mass of the spring and the pan is negligible. When pressed slightly and released the mas 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 = 10 m//s^(2)`)

10.0 cm

Any value less than 12.0 cm

4.0 cm

8.0 cm
