A 450 kg satellite orbits at a distance from the Earth's center of about 6.5 Earth radii. What gravitational force does the Earth exert on the satellite?

2. Homework Equations

Gravitational force= G* ((mMe)/(r^2))

3. The Attempt at a Solution

G times mass times earths mass divided by radius squared.

G= 6.67E-11

m= 450 kg

Me(earths mass)= 5.98E24

r(radius)= 6.5 x 6370 (earths radius)

I inserted this into the equation but came up with the wrong answer it said. I don't know what I'm doing wrong and am getting very frustrated !
