Question

$N$ identical beads are resting on a smooth horizontal wire which is circular at the end with radius $r = 0.5 m$ as shown in the figure. Find the minimum velocity which should be imparted to the first bead such that n $^{t h}$ bead will fall in the tank after completing full circle in vertical plane as shown in the figure. Take all the collision between the collisions between the beads elastic. ( $e = 1$ )
