Physics - SHM Question with Solution | TestHub

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$3 \mathrm{s}$. When the mass$m$is increased by$1 \mathrm{kg}$, the time period of oscillations becomes$5 \mathrm{s}$. The value of$m$in$\mathrm{kg}$isNEET 2016 (Phase 2)
