Final answer:
The gravitational force on Satellite B, which is four times farther from Earth than Satellite A, is 1/16 the force on Satellite A due to the inverse square law of gravitation.
Step-by-step explanation:
The magnitude of the gravitational force between two objects, such as Earth and a satellite, is inversely proportional to the square of the distance between them. This is known as the inverse square law. If Satellite B is four times the distance from Earth compared to Satellite A, the gravitational force on Satellite B will be 1/16 the force on Satellite A. This is because when you square the distance factor 4 (since Satellite B is four times farther away), you get 42, which is 16. Therefore, the force of gravity on Satellite B is 1/16 that of Satellite A.
