Answer:
5.6 x 10^9 J
Explanation:
mass of satellite, m = 571 kg
r1 = 2 R
r2 = 3R
R = 8.8 x 10^6 m
mass of planet, M = 7.76 x 10^24 kg
The formula for the work done is given by
[tex]W=GMm\left ( \frac{1}{r_{1}}-\frac{1}{r_{2}} \right )[/tex]
Where, G is universal gravitational constant, G = 6.67 x 10^-11 Nm^2/kg^2
[tex]W=GMm\left ( \frac{1}{2R}-\frac{1}{3R} \right )=\frac{GMm}{6R}[/tex]
[tex]W=\frac{6.67\times10^{-11}\times7.76\times10^{24}\times 571}{6\times 8.8\times10^6}[/tex]
W = 5.6 x 10^9 J
