Figure shows a horizontal rod AB which is free to rotate about two smooth bearing system Two identical uniform rods each of mass m are attached to rod AB symmetrically about the centre of mass O of the rod AB All the dimensions are given in the figure The system is rotating with constant angular velocity in such a way that the upper rod is coming outward from the plane of the paper in the position shown Gravity can be assumed to be absent in the experiment Then choose the correct option s A The hinge reaction at A on the rod AB is downward B The hinge reaction at B on the rod AB is upward A L b C The hinge reaction at B on the rod AB is downward D The angular momentum of the system about point O is NOT along the rod AB
