A uniform rod A B of length ' L ' and mass ' M ' is pivoted at the centre ' O ' in such a way that it can rotate in the vertical plane as shown in the figure. An insect of the same mass falls vertically with speed ' v ' on the horizontal rod at a point ' C ' which is the midpoint of O and B . Immediately after falling, the insect moves towards the end B such that the rod rotates with constant angular velocity ' '. If
