A rod OA of uniform mass density and length 'L' is hinged at 0 in a vertical plane Another square plate of same mass is attached with a point A of the rod as shown in the figure. In case (i) square plate is free to rotate about point A and in case (ii)square plate is fixed at point A. Now system is allowed to oscillate in vertical plane such that axis of rotation is horizontal and passing through point
