A satellite of the mass 500kg is boosted from an orbit of altitude 10,000 km to one of altitude 20,000km. Given that the diameter of the earth is 12,756km, its mass as 5.97x1024. calculate the change of GPE of the satellite
Ep=-Gm1m2/r + altitude
The Attempt at a Solution
Ep=6.672x10-11x500x5.97x1024/(0.5x12756000m) + altitude
Am i wrong? I dont know how to do this.
