Find the minimum velocity which should be imparted to the first bead such that nth bead will fall in the tank after completing full circle in vertical plane as shown in the figure. Take all the collisions between the beads elastic (e = 1).

A particle of mass m makes an elastic head on collision with a stationery particle of mass 2m. If initial kinetic energy is moving particle is 6 j then during the impact
