NONUNIFORM ARCHIMEDES



A planet with VERY inhomogeneous mass distribution may have a very non-uniform gravitational field on its surface, and equipotential surfaces of the field will not be flat as depicted by black lines in the picture above. Consider a body of water (lake) on the surface of such a planet. Discuss flotation of bodies in such a liquid. Can you formulate a generalized Archimedes law? (As an example consider flotation of a solid sphere.)

This this problem was inspired by discussions with Gyozo Egri, Marton Kormos and Bence Kocsis.
