Two spheres are placed at a distance of 10 m from each other. The force of gravity between them is 6.673x10 to the (9)N. If one of the spheres is 4 times as massive as the other what are their masses in Kg?

the gravitational constant G =6.67•10⁻¹¹ N•m²/kg²,
F=6.673•10⁻⁹ N
R=10 m
F =G•m₁•m₂/R²= G•4m•m/R²= G•4m²/R²
m=sqrt{F R²/4G)=…
