A satellite has kinetic energy $K$ , potential energy $V$ and total energy $E .$ Which of the following statements is true?

Options:

Answer:

Solution:

As we know that for the earth and satellite system Kinetic energy, $K = \frac{GM m}{2 a}$ Potential energy, $V = - \frac{GM m}{a}$ and total energy, $E = - \frac{GM m}{2 a}$ where, $a =$ radius of the orbit of the satellite and $m =$ mass of the satellite On the basis of above three expressions for the energies, we have $K = \frac{GM m}{2 a} = - (- \frac{GM m}{2}) = - \frac{V}{2}$
