Three solids sphere each of mass m and diameter d are stuck together such that the lines connecting the centers from an equilateral triangle of side of length d. The ratio `I_(0)/I_(A)` of moment of inertia `I_(0)` of the system about an axis passing the centroid and about center of any of the spheres `I_(A)` and perpendicular to the plane of the triangle is

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)
