NASA wishes to send a 33 kg satellite into orbit 30,000 km above the SURFACE of the Earth. Calculate the gravitational field at that altitude.

Question

anonymous · Answer

G=6.67E-11
Mass of earth = 5.98*10^24
radius of earth =6.37*10^6

anonymous · Answer

The gravitational field $g$ a distance $R$ from the center of mass of an object of mass $m$ can be derived from Newton's law of gravitation.  The relationship you'll want is $$g = \frac{GM}{r^2}.$$

anonymous · Answer

Of course, I meant$$g = \frac{GM}{R^2}$$

anonymous · Answer

gravitational field = gravitational force /mass of the object
therefore
g=Gme/r2

where r is the distance from the surfaceof the earth+the radius of the earth
