 \\

The total energy of the satellite in terms of  g_{0} , acceleration due to gravity at the earth's surface = \huge \frac{ - m g_{0} {r}^{2} }{2(r + h)}

Explanation:

Hint:-

  • We know that the Total energy of a satellite = sum of its potential energy and kinetic energy
  • The potential energy of a system due to Earth's gravitational pull is always -ve.
  • The acceleration due to gravity is the constant acceleration acting on a body above the Earth's surface.

\Huge\underline{\overline{\mid{\bold{\red{\tt{Solution}}\mid}}}}

Total energy of satellite is:-

E = \large\frac{ - GmMm}{2(r + h)} ....(1)

Here, E is the total energy of the satellite

G is the gravitational constant

M is the mass of the Earth

m is the mass of the satellite

R is the radius of the Earth

h is the height of satellite from the Earth’s surface

Now,

Acceleration due to gravity,  g_{0} = \large\frac{GM}{ {r}^{2} } ....(2)

From (2)

 g_{0} {r}^{2} = GM

\therefore E = \large\frac{ -  g_{0} {r}^{2}  m}{2(r + h)}
