A satellite weighs 17000 N on the surface of the Earth. What would be it's weight two Earth radii above the surface of the Earth?

1889N

Explanation:

r=the Earth's radius

r=two Earth radii above the surface of the Earth=3r

So r = r/3

Find the value of Gm/r²

F=Gm/r²

17000=Gm/r²

17000=Gm/(r/3)²

17000=Gm/(r²/9)

17000=9Gm/r²

1888.89=Gm/r²
