Question

If the gravitational force between two masses was 10

newton at a certain distance, what would the gravitational force

become if that distance was doubled?​

Answer 1

Answer:

Let the two bodies have masses m

=0.25

So, force of attraction decreases by 75%.

Answer 2

Answer:

If the gravitational force between two masses was 10 newtons at a certain distance, what would the gravitational force become if that distance was doubled? ... Our new force one when the distance has doubled is equal to multiplied by one multiplied by two divided by two squared.
