Now the pair decide to solve a homework problem to check their understanding. The densest known element is osmium with a density of= 22.4 g/cm³. Suppose two small spheres of osmium with radii2.70cm are in contact with each other. Find the gravitational force of attraction between them, given that

G= 6.6710¹¹Nm²/kg².

Recall that

=

and

V_sphere=
