Question description

The densest known element is osmium with a density of ρ = 22.4 g/cm3. Suppose two small spheres of osmium with radius 3.00 cm are in contact with each other. 

Find the gravitational force of attraction between them.In proportion to what power of r does the smallest separation of the sphere centers vary? So the attraction between the spheres of maximum mass at smallest separation increases as r to what power?
