Question 7.
The formula above gives the gravitational force, Fg, in Newtons, between two objects with
masses m, and m2, where G is the gravitational constant and ² is the square of the distance, in
meters, between the two objects. Which of the following expresses the distance r between the two
objects in terms of the other quantities? (Show your work).
