What is the gravitational potential energy of the earth and a satellite of mass `m=100kg` orbiting close to the earth's surface ?

Explanation

To find the gravitational potential energy (U) of the Earth and a satellite of mass \( m = 100 \, \text{kg} \) orbiting close to the Earth's surface, we will use the formula for gravitational potential energy:

\[ U = -\frac{G M m}{r} \]

where:
- \( G \) is the universal gravitational constant, approximately \( 6.674 \times 10^{-11} \, \text{N m}^2/\text{kg}^2 \),
