A body on the surface of the Earth weighs 400 lb.The radius of the Earth is about 4,000 miles.If this same body were placed on a 4,000-mile high tower,its weight would be 200 lb.

Question

Quizplus · Accepted Answer

The weight of an object at a height h above the surface of the Earth is given by the formula W = (G*M*m)/(R+h)^2, where G is the gravitational constant, M is the mass of the Earth, m is the mass of the object, R is the radius of the Earth, and h is the height above the surface. Plugging in the given values, we get W = (G*6E24*400)/(4000+4000)^2 = 355.8 lb, which is not equal to 200 lb. Therefore, the statement is false.
