A uniform rod of mass 40 kg and length 3 m has moment of inertia about an axis AB passing through one end and perpendicular to the rod. A solid sphere of mass 10 kg and radius R has the same moment of inertia about an axis parallel to AB and located 3 m from the sphere's centre, as shown in the source figure. If R = √(α ÷ 2) m, find α.
