Determine the value that has the largest total energy. Assuming that the orbirts are circular.

(a) 1000 kg satellite at geosynchronous orbit
(b) 1000 kg satellite in low earth orbit—roughly 300 km
(c) 500 kg satellite at geosynchronous orbit
(d) A 500 kg satellite in low earth orbit—roughly 300 km
(e) not given enough information

I say c,am i right?
