2 A smooth ball of mass m moving with a uniform velocity v strikes a smooth uniform rod AB of equal mass m lying on a frictionless horizontal table The ball strikes the rod at one end A perpendicular to the rod as shown in the figure The collision is perfectly elastic Some physical quantities pertaining to this situation are given in Column 1 while their values are given in Column II in a different order Match the values in Column ll and the quantities in Column l m m Column l A The ratio of final kinetic energy of ball its initial kinetic energy B The ratio of impulsion delivered to the rod to initial momentum of ball The ratio of angular momentum of rod about its centre of mass to the initial angular momentum of the ball about the centre of mass of the rodr D The ratio of final kinetic energy of rotation of the rod Column II e
