alleryTotal energy of a satellite in circular orbit equals:
AHalf of potential energy
BTwice the potential energy
C+ Kinetic energy
D- Kinetic energy
Answer & Solution
Correct answer: D. - Kinetic energy
**For circular orbit:** KE = GMm/(2r), PE = -GMm/r, Total E = -GMm/(2r) = -KE.
So total energy equals negative kinetic energy.
Total is negative, indicating bound orbit.
