Asked by Erika

The mutual gravitational attraction between two masses in space is 686 Newtons. What is the new gravitational force between these masses if the distance between them is increased by a factor of 5.6?

To be graded correctly, enter the new weight in Newtons (numbers only, no text), rounded off to one decimal place. Your answer must be correct within ±0.5 Newtons.



I got 21.875 or 21.9
