1. The problem statement, all variables and given/known data Communications satellites are placed in a circular orbit where they stay directly over a fixed point on the equator as the earth rotates. These are called geosynchronous orbits. The altitude of a geosynchronous orbit is 3.58e7 m. 2. Relevant equations v=2∏r/T a=(v^2)/r 3. The attempt at a solution In the previous problem, I was asked to calculate the period of the satellite, which is obviously 24 hours. I figure that g is another form of radial acceleration (both point to the center of earth). Therefore, I calculated v using the period equation. Once I got v I used the radial acceleration equation to arrive at my answer for g. It's wrong though- can anyone explain why and set me on the right track?
