A bar of mass m and length l is in pure translational motion with its centre of mass moving with a velocity v. It collides and sticks to another identical bar at rest as shown in the figure. Assuming that after the collision the system of the two bars becomes one composite bar of length 2l, then the angular velocity of the composite bar will be

`(3v)/(4l)`, anti - clockwise

`(4v)/(3l)`, anti- clockwise

`(3v)/(4l)`, clockwise

`(4v)/(3l)`, clockwise
