A satellite has a mass of 101 kg and is located at 1.99x10^6 m above Earth's surface.
(a) What is the potential energy of the satellite at this location?

(b) What is the magnitude of the gravitational force on the satellite?

for potential energy, I was using the equation PE=mgy, but i needed to find the correct g to use. so i tried g=(GMeM)/(r^2), but apparently that's not right. what am i doing wrong? and how do i find the magnitude of the grav. force?
