Asatellite is put into an orbit at a distance from the center of the earth equal to twice the distance from the center of the earth to the surface. if the satellite had a weight at the surface of 4000 n, what is the force of gravity (weight) of the satellite when it is in its orbit? give your answer in newtons, n.

995 N

Explanation:

Weight of surface, w= 4000N

Gravitational constant, g, is taken as 9.81 hence mass, m of surface is W/g where W is weight of surface

m= 4000/9.81= 407.7472

Using radius of orbit of 6371km

The force of gravity of satellite in its orbit,

Where and

F= 995.01142 then rounded off

F=995N
