A 20 pound barbell is brought from earth to the International Space Station(ISS). How does this trip affect the gravitational force between the two ends of the barbell? Assume the distance between the barbell end masses does not change.
--
The gravitacional forte between the ends decreases.
The gravitational force between them decreases by one huit
The gravitational force between them doubles
The gravitational face between the ends increases
The gravitational force between the ends remains the same
