A thin uniform rod, pivoted at , is rotating in the horizontal plane with constant angular speed , as shown in the figure. At time, , a small insect starts from and moves with constant speed with respect to the rod towards the other end. It reaches the end of the rod at and stops. The angular speed of the system remains throughout. The magnitude of the torque on the system about , as a function of time is best represented by which plot
