A space probe of mass m = 200 kg is moved from Earth's surface (r1 = R_E = 6.37 x 10^6 m) to an altitude h = 2*R_E (r2 = 3*R_E). Taking M_E = 5.97 x 10^24 kg and G = 6.67 x 10^-11 N m^2/kg^2, what is the change in gravitational potential energy delta U of the probe?

8.33 x 10^9 J 1.25 x 10^10 J 4.17 x 10^9 J 1.87 x 10^10 J

Correct Answer:

8.33 x 10^9 J
