An artificial satellite moving in a circular orbit around the earth has a total (kinetic + potential) energy ${E_0}$. Its potential energy is

A

$ - {E_0}$

B

$1.5\,{E_0}$

C

$2\,{E_0}$

D

${E_0}$

An artificial satellite moving in a circular orbit around the earth has a total (kinetic + potential) energy ${E_0}$. Its potential energy is

Potential energy $= 2 ×$ (Total energy) = $2{E_0}$
Because we know = $U = \frac{{ - GMm}}{r}$ and ${E_0} = \frac{{ - GMm}}{{2r}}$
