![]() X.33 If an object has a moment of inertia 19 kgm2 and the magnitude of its rotational angular. ![]() What will be the moment of inertia of a very thin spherical shell of the same mass and radius as that of the. So basically moment of inertia of a some small mass dm situated at a distance r from the axis is dm×r2. What is the rotational angular momentum of the sphere. The moment of inertia of a solid sphere is 10kgm2. We can see from above two expressions that moment of inertia of hollow sphere is greater than that of solid sphere. ![]() The moment of inertia of the hollow cylinder about its standard axis. So the moment of inertia of hollow sphere is 2/3mr2 and that of solid sphere is 2/5 mr2. Hint: Moment of Inertia (M.I.) of the solid sphere along its diameter is $I = \dfrac$ which is the moment of inertia of hollow sphere along its diameter also be careful about the mentioned axis about which the moment of inertia is being written these small checks while attempting a question can save you from silly mistakes in the exam. An axis along its diameter is an axis of spherical symmetry through its centre of mass. ![]()
