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 $$g_0$$, the value of acceleration due to gravity at the earth's surface, is

A

$$-\frac{mg_0R^2}{2(R+h)}$$

B

$$\frac{2mg_0R^2}{R+h}$$

C

$$-\frac{2mg_0R^2}{R+h}$$

D

$$\frac{mg_0R^2}{2(R+h)}$$
