(a) Newton’s Law of Gravitation states that two bodies with masses 
and 
attract each other with a force
where r is distance between the bodies and G is the gravitational constant. If one of the bodies is fixed, find the work done needed to move the other from
to
.
(b) Compute the work required to launch a 1000-kg satellite vertically to a height of 1000 km. You may assume that earth’s mass is 
kg and is concentrated at its center. Take the radius of the earth to be 
m and
