Four solid spheres each of mass m and radius a, have their centers on the vertices of a square whose side is b. Find moment of inertia about the given axis?
(Assume spheres are connected using a light frame)
(a) $m\left({8a^2\over5}+2b^2\right)$
(b) $m\left({8a^2\over5}+4b^2\right)$
(c) $m\left({4a^2\over5}+2b^2\right)$
(d) $m\left({4a^2\over5}+b^2\right)$
