Dear Student,
Let Mass of the Earth be Me
Mass of the satellite be m
Radius of the Earth be Re
Universal gravitational constant, G = 6.67 × 10–11 Nm2kg–2
Height of the satellite = R
Total energy of the satellite at height R
Orbital velocity of the satellite,
Total energy of height,
The negative sign indicates that the satellite is bound to the Earth. This is called bound energy of the satellite.
Energy required to send the satellite out of its orbit = – (Bound energy)
