Concept explainers
Recall that the gravitational force exerted by the Earth on an object is called the object’s weight (or more precisely, its Earth Weight). If an object of mass m is on the surface of the Earth weight). If an object of mass m is on the surface of the Earth (mean sea level), then the magnitude of its weight is mg, where g is the acceleration due to gravity at the Earth’s surface. A more general formula for the magnitude of the gravitational force that the Earth on an object of mass m is
(a) Use the binomial series for
(b) Show that if
(c) Show that if
(d) If we assume that the Earth is a sphere of radius
