1.	A rod of mass 100 g and length 1.0 m makes an angle 30^(@) with the axis passing through its centre. Find (i) the moment of inertia of the rod about the give axis. (ii) If the rod rotates with an angular velocity of 2.0 rad.^(-1) about the given axis find the rotational kinetic energy of the rod.
