A bar of mass m, length is in pure translatory motion with its centre of mass velocity . It collides with and sticks to another identical bar at rest as shown in figure. Assuming that after collision it becomes one composite bar of length 2l, the angular velocity of the composite bar will be.
(A) 3v/4l anticlockwise
(B) 4v/3l anticlockwise
(C) 3v/4l clockwise
(D) 4v/3l clockwise
