A Satellite Weighs 17000 N On The Surface Of The Earth What Would Be Its Weight Two Earth Radii Above The Surface Of The Earth class=

Answer:

1889N

Explanation:

r[tex]_{a}[/tex]=the Earth's radius

r[tex]_{b}[/tex]=two Earth radii above the surface of the Earth=3r[tex]_{a}[/tex]

So r[tex]_{a}[/tex] = r[tex]_{b}[/tex]/3

Find the value of Gm/r[tex]_{b}[/tex]²

F=Gm/r²

17000=Gm/r[tex]_{a}[/tex]²

17000=Gm/(r[tex]_{b}[/tex]/3)²

17000=Gm/(r[tex]_{b}[/tex]²/9)

17000=9Gm/r[tex]_{b}[/tex]²

1888.89=Gm/r[tex]_{b}[/tex]²
