2. A thin rod of length 10m is in the x-y plane parallel to the x axis. Its centre is at the point (3,2) .A force of 100 N in the x-y plane is applied at its right end at an angle of 30o from the x-axis. An equal and opposite force is applied at its other end.
(i) Make a diagram showing the x-and y axes, the rod, and the forces on it.
(ii) Calculate the torque due to these forces with respect to the origin with respect to the centre to the rod, and with respect to each end of the rod.
(iii)Why all the torques are equal?
