Two spheres of the same material and same radius "r" are touching each other. If the gravitational force of attraction between them is directly proportional to r^4, then the value of n is

Spheres of the same metarial and same radius r are touching each other. Show that grevitational force between them is directly proportional to r^(4) .

Two speres of radii r and 2r touching each other the force of attraction betweeen them is proportional

Two uniform solid spheres of same materical and same radius are touching each other density is 'rho' then find out gravitational force between them .

Two solid sphere of same size of a metal are placed in contact by touching each other prove that the gravitational force acting between then is directly proportional to the fourth power of their radius.
