O 9 A thin uniform rod pivoted at O is rotating in the horizontal plane with constant angular speed as shown in the figure At time t 0 a small insect starts from O and moves with constant speed v with respect to the rod towards the other end It reaches the end of the rod at t T and stops The angular speed of the system remains throughout The magnitude of the torque 7 about O as a function of time is best represented by which plot A C 7 171 T T t B D 171 O T 33 2012 t t
