```							Given in the question :-Along the tangent ,The two bodies of mass m radius r are moving.Refer to the attachment Here moment of inertia of one body about the axis(XY) passing by tangent. I = (2/5)mr²  Now, Moment of inertia of first axis parallel to the other axis r = I + mr^2r = (2/5) mr² + mr² r = (7/5)mr² .Hence the moment of inertia of a pair of sphere is (7/5) mr²
