CENTRE OF MASS OF UNIFORM HEMI-SPHERICAL SHELL

CENTRE OF MASS OF SOLID HEMI-SPHERE

STATEMENT -1 : Gravitational field inside a spherical mass shell is zero even if the mass distribution is uniform or non-uniform. and STATEMENT -2 : A mass object when placed inside a mass spherical shell, is protected from the gravitational field of another mass object placed outside the shell.

The gravitational force between a hollow spherical shell (of radius R and uniform density) and a point mass is F. Show the nature of F vs r graph whee r is the distance of the point form the centre of the hollow spherical shell of uniform density.
