Four solid spheres, each of mass (m) and...

Four solid spheres, each of mass (m) and diameter (d) are stuck together such that the lines joining the centres form a square of side length (d). The ratio of `I_(0)` & `I_(A)` , where `I_(0)` is the moment of inertia of the system about an axis through the centre of the square and `I_(A)` is moment of inertia of the system about the centre of any one of the spheres, is equal to (both axes are perpendicular to plane of paper)
