The game of Jacks is played with pieces like those shown to the right, consisting of four small spheres at the ends of two perpendicular rods of length L and mass M. The piece is spun as shown about an axis through the third perpendicular rod of length L and mass M. Assume that the mass of each sphere is M/4, and that the rotational inertia of a rod about an axis perpendicular to the center of the rod is ML2/12. The rotational inertia of the Jacks piece is closest to
A) 5/12 ML2 B) 1/3 ML2 C) 1/2 ML2 D) 13/12 ML2
