For a satellite moving in an orbit around the earth, the ratio of kinetic energy to potential energy is
$2$
$\frac{1}{2}$
$\frac{1}{{\sqrt 2 }}$
$\sqrt 2 $
For a satellite moving in an orbit around the earth, the ratio of kinetic energy to potential energy is
For a moving satellite kinetic energy $ = \frac{{GMm}}{{2r}}$
Potential energy $ = \frac{{ - GMm}}{r}$
$\frac{{{\rm{Kinetic}}\,{\rm{energy}}}}{{{\rm{Potential}}\,{\rm{energy}}}} = \frac{1}{2}$
