A uniform bar of length 6 a & mass 8 m lies on a smooth horizontal table. Two point masses m & 2m moving in the same horizontal plane with speeds 2 v and v respectively strike the bar as shown & stick to the bar after collision.
Angular velocity of the rod about centre of mass of the system is :
(A) v/5a
(B) v/15a
(C) v/3a
(D) v/10a
