satellite B is twice the distance between the Earth and satellite A. Which of
the following correctly compares the force of Earth's gravity on the satellites?
A. The gravitational force acting on satellite B is larger than the
gravitational force acting on satellite A.
B. It cannot be determined.
C. The gravitational force acting on satellite B is equal to the
gravitational force acting on satellite A.
D. The gravitational force acting on satellite B is less than the
gravitational force acting on satellite A.
