Three masses of `500 g`, `300 g` and `100 g` are suspended at the end

1.	Three masses of `500 g`, `300 g` and `100 g` are suspended at the end of a spring as shown and are in equilibrium. When the `500 g` mass is removed suddenly, the system oscillates with a period of `2 s`. When the `300 g` mass is also removed, it will oscillate with period `T`. Find the value of `T`.
Answer» Correct Answer - A::C `2 = 2pi sqrt((0.3 + 0.1))/(k))` ….(i) `T = 2pi sqrt ((0.1)/(k))` …(ii) Solving these two equation we get, `T = 1 s`
