WebFeb 3, 2024 · Earth is surrounded by a system of magnetic fields, called the magnetosphere. The magnetosphere shields our home planet from harmful solar and cosmic particle radiation, but it can change shape in response to incoming space weather from the Sun. Earth’s internal magnetism creates a region around the planet known as the … Websphere and R is the radius of the sphere. {b) Given the moment of inertia of a disc of mass Mand radius R about any of its diameters to be MR2/4, find its moment of inertia about an axis normal to the disc and passing through a point on its edge. Ans. Given, (a) The moment of inertia (M.1.) of a sphere about its radius= 2MR2/1 0 r11,.:-.
