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 mis increased by 1 kg, the time period of oscillations becomes 5 s. The value of m in kg is - VgyanHub
