Question 1104047: The force of attraction between the earth and some object is called the weight of that object. The law of gravitation states, then, that the weight of an object is inversely proportional to the square of its distance from the centre of the earth. If a person weighs 170 lb on the surface of the earth (assume this to be 3960 mi from the centre), how much will he weigh 1700 mi above the surface of the earth?

W%2F170 = 3960%5E2%2F%283960%2B1700%29%5E2.


Solve the proportion to find "weight" W under the question.
