An artificial satellite moves in a circular orbit around the earth. Total energy of the satellite is given by \(E\). The potential energy of the satellite is
- A \(-2 E\)
- B \(2 E\)
- C \(\frac{2 E}{3}\)
- D \(-\frac{2 E}{3}\)
Answer & Solution
Correct Answer
(A) \(-2 E\)
Step-by-step Solution
Detailed explanation
We know that The potential energy of the satellite \[ U=-\frac{G M_{e} m}{R_{0}} \] The kinetic energy of the satellite \[ K=\frac{1}{2} \frac{G M_{e} m}{R_{e}} \] The total energy…
