tolong dong jawabin pakai caranya

Fs = F grav
mv² / (R + 2R) = GmM / (R + 2R)²
mv² / (3R) = GmM / (9R²)
v² = GM(3R) / (9R²)
    = GM / (3R) ← Jawaban: B.

Fsentripetal = Fgravitasi
m satelit [tex] \frac{v}{R+2R} ^{2} = [/tex] G. [tex] \frac{Mbumi . m satelit}{3R^{2}} [/tex]
[tex] v^{2} = \frac{G.M.3R}{9R^{2}} [/tex]
[tex] v^{2} = \frac{G.M}{3R} [/tex]
