SUMMARY
The gravitational force on an object at a distance of 4R from the center of a planet can be calculated using Newton's Law of Universal Gravitation. The force decreases with the square of the distance from the center of the planet. Specifically, if the weight of the object on the surface is W, the gravitational force at 4R is W/16. This conclusion is derived from the inverse square law of gravitation.
