At a certain distance from the center of the Earth, a 5.0-{\rm kg} object has a weight of 3.5N.
(a) Find the distance?
(B) If the object is released at this location and allowed to fall toward the Earth, what is its initial acceleration?
(c) If the object is now moved twice as far from the Earth, by what factor does its weight change?
(d) By what factor does its initial acceleration change?
