1. The problem statement, all variables and given/known data Synchronous communications satellites are placed in a circular orbit that is 3.59 X 10^7m above the surface of the earth. What is the magnitude of the acceleration due to gravity at this distance? 2. Relevant equations F=G M1M2 / R^2/ mp g= GMe / r^2 r= Re + H w=mg g=w/m 3. The attempt at a solution I tried to put the numbers in the "g= GMe / r^2" equation, which turns out to be g= 6.673 X 10^-11 X 5.9742 X 10^24 /( 3.59 X 10^7)^2 But the answer that I got is wrong. Can someone please help me fix my mistakes and help me get the right answer?
