Problem

Two identical solid spheres, each of mass mm and radius RR, are connected by a light rigid rod of length 3R3R that joins their centers. Determine the rotational inertia of the system about an axis that passes through the center of one sphere and is perpendicular to the rod. (a) 475 mR2\dfrac{47}{5}\,mR^{2} (b) 45 mR2\dfrac{4}{5}\,mR^{2} (c) 495 mR2\dfrac{49}{5}\,mR^{2} (d) 95 mR2\dfrac{9}{5}\,mR^{2}
