SUMMARY
The gravitational potential energy (U) of a satellite in a circular orbit can be calculated using the formula U = -GMm/r, where G is the gravitational constant, M is the mass of the Earth, m is the mass of the satellite, and r is the radius of the orbit. In this case, the radius is specified as 3Re, where Re represents the radius of the Earth. The mass of the satellite is given as 5.00 x 10^2 kg. To compute U, one must substitute the appropriate values for G, M, and r into the equation.
