Consider the following four objects: a hoop, a flat disk, a solid sphere, and a hollow sphere. Each of the objects has mass M and radius R. The axis of rotation passes through the center of each object, and is perpendicular to the plane of the hoop and the plane of the flat disk. If the objects are all spinning with the same angular momentum, which requires the largest torque to stop it? (a) the solid sphere (b) the hollow sphere (c) the hoop (d) the flat disk (e) both the solid and the hollow spheres
