Physics - SHM Question with Solution | TestHub

A mass of $2.0\mathrm{kg}$ 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 mass executes a simple harmonic motion. The spring constant is $200\mathrm{N}/\mathrm{m}$. What should be the minimum amplitude of the motion so that the mass gets detached from the pan (take $g=10\mathrm{m}/{\mathrm{s}}^2$ ).
