A mass of 2 kg is put on a flat pan attached to a vertical spring fixed on the ground as shown in figure. The mass of the spring and the pan is negligible. When pressed slightly and released the mass executes a SHM. The spring constant is 200 N/m. What should be the minimum amplitude of motion, so that the mass gets detached from pan? [Given, g=10m/s^2]

A body of mass m is attached to the lower end of a spring whose upper end is fixed. The spring has negligible mass. When the mass m is slightly pulled down and released, it oscillates with a time period of 3s. when the mass m is increased by 1 kg the time period of oscillations becomes 5s. Then value of m in kg is
