A ring of mass `m` and radius `r` is melted and then moulded into a sphere. The moment of inertia of the sphere will be

Three spheres, each mass M and radius R, are arranged as shown in the figure . The moment of inertia of the system will be

A sphere of mass 10 kg and radius 0.5 m rotates about a tangent. The moment of inertia of the sphere is

A disc of radius R and thickness has moment of inertia / about an axis passing through its centre and perpendicular to its plane. Disc is melted and recast into a solid sphere. The moment of inertia of a sphere about its diameter is

A sphere of mass 10 kg and radius 0.5 m rotates about a tangent. The moment of inertia of the solid sphere about tangent is

From a uniform sphere of mass M and radius R a cavity of diameter R is created as shown. Find the ratio of moment of inertia of the sphere left about "AA"' and BB' .

Two spheres of same mass and radius are in contact with each other. If the moment of inertia of a sphere about its diameter is I, then the moment of inertia of both the spheres about the tangent at their common point would be

Two spheres of same mass and radius are in contact with each other. If the moment of inertia of a sphere about its diameter is I, then the moment of inertia of both the spheres about the tangent at their common point would be
