Problem 5. Two balls of mass M and m are connected by a rigid mass less rod. Each mass is basically a point mass and their centers are a distance
L apart. For an axis perpendicular to the rod (dashed line in figure), show that the system has a minimum moment of inertia when the axis passes through the center of mass. Find this moment of inertia.
