## Homework Statement

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 5.97x10

^{24}. calculate the change of GPE of the satellite

## Homework Equations

E

_{p}=-Gm

_{1}m

_{2}/r + altitude

## The Attempt at a Solution

E

_{p}=6.672x10

^{-11}x500x5.97x10

^{24}/(0.5x12756000m) + altitude

Am i wrong? I don't know how to do this.
