YOU are siting next to a person who has twice as much weight. you get up and move one seat over, doubling your distance from them, did the gravitational force between you increase, decrease or stay the same.

decrease

Explanation:

Gravitational Force or gravitational interaction is the force that arises from the mutual interaction between two bodies. Attractive and never repulsive, it is what makes it possible to stand. That's because the Earth exerts a gravitational pull on the bodies.

Newton found that the gravitational force was inversely proportional to the square of the distance between the masses, in other words, the further apart the objects are, the lower the force of attraction between them and the force decreases rapidly with increasing distance. In this case, we can say that in the situation shown in the question above, if you get up and move a seat, doubling your distance from them, the gravitational force between you decreases.

The gravitational force is decreased by 1/4

Explanation:

Since gravitational force is inversely proportional to the square of the separation distance between the two interacting objects, more separation distance will result in weaker gravitational forces. So as two objects are separated from each other, the force of gravitational attraction between them also decreases. If the separation distance between two objects is doubled (increased by a factor of 2), then the force of gravitational attraction is decreased by a factor of 4 (2 raised to the second power). If the separation distance between any two objects is tripled (increased by a factor of 3), then the force of gravitational attraction is decreased by a factor of 9 (3 raised to the second power).
