The acceleration due to gravity at a distance r from the center of the Earth is given by:

g = GM/r^2 (eq.1)

… where G is the gravitational constant, and M is the mas of the Earth.

At the surface of the Earth, r = R (R = radius of the Earth) and g = 9.8m/s/s. Putting this into the equation gives you:

9.8 = GM/R^2 (eq.2)

When the height above the Earth is equal to the radius of the Earth, then r = 2R. Putting that into the equation gives:

g = GM/(4R^2) (eq.3)

Substitute euqation 2 into equation 3 and solve.
