Calculate the gravitational force of attraction between a 4 kg mass and a 5 kg mass separated by a distance of 0.8 m. To receive full credit, you
must write the equation you are using, show what you value with units
that you are substituting for each variable, and state your final answer in
units. *

How is the gravitational force related to the distance between two objects?
