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

Question

(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?

Answer 1

Correct. You can easily calculate this. You can also see this as follows. All the energies are negative, so the object with the largest energy is that object which requires the least energy to escape to infinity.
