Question

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
