Solve the all parts of following question given below:
Question: Two Earth satellites, A and B, each of mass m = 910kg, are launched into circular orbits around the Earth's center. Satellite A orbits at an altitude of 4500km, and satellite B orbits at an altitude of 10100km.
Part A: What are the potential energies of the two satellites?
Part B: What are the kinetic energies of the two satellites?
Part C: How much work would it require to change the orbit of satellite A to match that of satellite B?
I want help to find the potential energies of the two satellites.
