A) twice the kinetic energy of the satellite
B) half the kinetic energy of the satellite
C) twice the potential energy of the satellite
D) equal to the potential energy of the satellite
E) half the potential energy of the satellite
Correct Answer: E
Solution :
Potential energy\[=-\frac{GMm}{r}\] Total energy \[=-\frac{GMm}{2r}\] Hence, the total energy of a circularly orbiting satellite is half the potential energy of the satellite.
