A bead of mass $m$ can slide on a frictionless fixed ring of very large radius $r$. With the help of two identical strings of force constant $k,$ it is connected to two diametrically opposite nails $A$ and $B$ each of which are at distance $0.5r$ from the centre $O$ of the ring. The relaxed length of each string is negligible as compared to the radius of the ring. The bead is given a small velocity. What can you predict for further motion of the bead before any of the strings strikes a nail?
