A rod CD of length L and mass m is placed horizontally on a frictionless horizontal surface as shown. A second identical rod AB which is also placed horizontally ( perpendicular to CD) on the same horizontal surface is moving along the surface with a velocity v in a direction perpendicular to rod CD and its and B strikes the rod CD at end C and sticks to it rigidity. Then,

1.	A rod CD of length L and mass m is placed horizontally on a frictionless horizontal surface as shown. A second identical rod AB which is also placed horizontally ( perpendicular to CD) on the same horizontal surface is moving along the surface with a velocity v in a direction perpendicular to rod CD and its and B strikes the rod CD at end C and sticks to it rigidity. Then,
Answer» VELOCITY of centre of mass of the system just after collision is `(v)/(4)` ANGULAR speed of system just after collision is `(2v)/(5L)` Velocity of centre of mass of the system just after collision is `(v)/(2)` angular speed of system just after collision is `(5L)/(3L)` Answer :B::C
