355615 In the situation in figure, a block of mass \(1\,kg\) is attached to a light spring of constant \({40 {~N} / {m}}\) whose other end is fixed to the roof of a building \(50\,cm\) above the smooth horizontal surface. Initially, spring is in natural length and vertical. When a force \({F=20 \sqrt{3} {~N}}\) is applied on the block, the block starts to move. The speed at the instant it breaks off the surface below it is \({\sqrt{10 n} {~m} / {s}}\). The value of \({n}\) is
