A point mass m A is connected to a point mass mB by a mass less rod of length l as shown in the figure. It is observed that the ratio of the moment of inertia of the system about the two axes BB and AA, which is parallel to each and perpendicular to the rod, is IAA/Imm = 3. The distance of the centre of mass of the system from the mass A is
