4. [-/2 Points] DETAILS MY NOTES Approximate the gravitational force of attraction between a 70.0 kg girl and a 90.0 kg boy if they are sitting 2.0 m apart In physics class. *Notice how small the answer is. The boy and girl are certainly not very attracted to each other. This is why the gravitational force between objects is normally ignored when drawing free- body diagrams. The force of gravity is incredibly small unless a very, very large mass is Involved (e.g. a planet)
