Determine the magnitude of the force of gravity acting on a 340 kg satellite, 850km above Earth's surface.

2. Relevant equations

So I dedcided to use the Universal Gravitation Law:

Fg = (Gm1m2)/d^2

3. The attempt at a solution

m1=5.98E24 (earth's mass)

m2=340kg (satellite)

G=6.67E-11

d=850,000m

After subbing them all into the formula I got 187,701N.

However the answer in the book is 2.1E2N.

So I'm not sure if I did it right... can you please check it?

Thanks
