N beads are restiog on a smooth horizontal wire which is circular at the end with radius r as shown in figure the masses of the beads are m, m//2,m//2.....,m//2^(n-1) respectively. Find the minimum velocity which should be iparted to the first bead of mass m such that the n^(th) bead wil fall in the tank shown in figure -40148.

1.	N beads are restiog on a smooth horizontal wire which is circular at the end with radius r as shown in figure the masses of the beads are m, m//2,m//2.....,m//2^(n-1) respectively. Find the minimum velocity which should be iparted to the first bead of mass m such that the n^(th) bead wil fall in the tank shown in figure -40148.
