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
