N beads identical beads are resting on a smooth horizontal wire which is circular at the end with radius r=0.5m as shown in the figure. 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).

Two identical blocks P and Q have mass m each. They are attached to two identical springs initially unstretched. Now the left spring (along with P) is compressed by 2 A and the right spring (along with Q) is compressed by A. Both the blocks are released simultaneously. They collide perfectly inelastically. Initially time period of both the block was T. The time period of oscillation of combined mass is

Two masses A and B of 3 kg and 2 kg are connected by a long inextensible string which passes over a massless and frictionless pulley. Initially the height of both the masses from the ground is same and equal to 1 metre. When the masses are released. Mass A hits the ground and gets stuck to the ground. Consider the length of the string as large, so that the pulley does not obstruct the motion of masses A and B
