Question

A uniform rod AB of length 7 m is undergoing general planar motion on a smooth horizontal surface such that, at some instant of time, velocities of its end point A and centre $C$ are both perpendicular to the rod and opposite in direction, having magnitude 11 $m / s$ and $3 m / s$ respectively as shown in the figure. Now consider that no external force and no external torque is acting on the rod. Then select CORRECT options, for the instant shown.
