A bar of mass M and length L is in pure translatory motion with its centre of mass velocity V. It collides with and sticks to a second identical bar which is initially at rest. (Assume that it becomes one composite bar of length \[2L\]). The angular velocity of the composite bar will be

A) \[\frac{3}{4}\frac{V}{L}\]clockwise    

B)                                \[\frac{4}{43}\frac{V}{L}\]clockwise

C) \[\frac{3}{4}\frac{V}{L}\] counterclockwise    

D) \[\frac{V}{L}\] counterclockwise
