A smooth rod of mass M, length L = 1 (m), is rotated at one end with a constant angular velocity w =3 (rad/s) as shown in the figure. At t=0, an insect of m = 0.02 (kg) moves from point O to the other end of the rod with a constant velocity of v = 2 (m/s) and stops at the end of rod. The angular velocity of the rod remains constant during the movement. Find the torque acting on the rod in (N.m) when the insect reaches to the end of rod (just before it stops).
