Why the total energy of satellite comes negative?

Why the potential energy of the satellite comes negative?

Which fact indicates that the total energy of electron is negative?

If the zero of potential energy is at infinity, the total energy of an orbiting satellite is negative of its kinetic/potential energy.

Choose the correct alternative : (a) If the zero of potential energy is at infinityn the total energy of an orbiting satellite is negative of its kinetic/potential energy. (b) The energy required to launch an orbiting satellite out of earth's gravitational influence is more/less than the energy required to project a stationary object at the same height (as the satellite) out of earth's influence.

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,

These both situation is truely shown in graph (D) 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

Obtain an expression of total energy of satellite revolving around the earth.
