A solid sphere will be in stable equilibrium if its centre of gravity lies

For a circular ring, centre of gravity lies

In order that a floating object be in a stable equilibrium its centre of buoyancy should be

Assertion : For a floating body to be in stable equilibrium, its centre of buoyancy must be located above the centre of gravity. Reason : The torque produced by the weight of the body and the upthrust will restore body back to its normal position, after the body is disturbed.

The moment of inertia of a solid sphere about an axis passing through its centre of gravity is (2)/(5)MR^(2) . What is its radius of gyration about a parallel axis at a distance 2R from the first axis ?

A bowl with a semi spherical base is designed such that its centre of gravity is located at the centre of curvature of the spherical part. Explain giving reasons, to which state of equilibrium the bowl belongs. If the bowl is filled with water upto the centre of gravity, explain how the equilibrium state would be affccted/unaffccted.

A cylinder and a hollow sphere are placed on a surface. If the height of the cylinder is equal to the diameter of the sphere, what is the ratio of the heights of centre of gravity of the cylinder and the sphere from the surfaced?

An object placed on the ground in the stable equilibrium. If the object is given a light push, then initially the position of centre of gravity

Centre of mass of a body is a point where its whole ______ acts whereasits centre of gravity is a point where its whole ________ acts
