NEET 2016 Phase 2 | Gravitation Question 24 | Physics

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

$${{m{g_0}{R^2}} \over {2\left( {R + h} \right)}}$$

$$ - {{m{g_0}{R^2}} \over {2\left( {R + h} \right)}}$$

$${{2m{g_0}{R^2}} \over {R + h}}$$

$$ - {{2m{g_0}{R^2}} \over {R + h}}$$
