I tried ur way and it doesn't work, after reading textbook, Etotal= -k, so I got it right with -2.7*10^33.
Another question:Two satellites are in geosynchronous orbit but in diametrically opposite positions. Into how much lower a circular orbit should one spacecraft descend if it is to catch up with the other after 10 complete orbits
I cant seem to get a number, I always get the answer with respect to radius.
How did you go about finding the answer? Reason why I didn't attempt to do it fully was because I knew there was tricky business with PEgravity. Never liked it.
As for your next question, the key word is geosynchronous. If you don't know what that means, it means that the satellite "hovers" at exactly the same spot above the planet. There's always a specific radius at which geosynchronous orbit is possible.
