Satellite Energy & Weightlessness

A satellite of mass m is orbiting the earth (of radius R) at a height h from its surface. The total energy of the satellite in terms of g0, the value of acceleration due to gravity at the earth's surface, is

Show answer and solution

Answer: (b)

$E = -\frac{GMm}{2(R+h)}$ .
Use $GM = g_0R^2$ : $E = -\frac{mg_0R^2}{2(R+h)}$ .
So the answer is (b).
