## Homework Statement

The problem states to calculate the height at which the gravity acceleration is 5x smaller than on the surface of the earth. So

g=9,81 m/s^2

R=6370km

M=6x10^24

**gamma**(don't know how to put it :P)=6,67x10^-11

## Homework Equations

g=gamma x M/(R+h)^2

## The Attempt at a Solution

I was pretty confident in this h = sqrt (g x R)/(gamma x M) but the result turned out bad.

The book I use states that the result is 7874 km. [/B]
