Two artificial satellites of the same mass are moving around the earth in circular orbits of different radii. In comparision to the satellite with lesser orbital radius, the other satellite with higher orbital radius will have:A. greater kinetic energyB. less potential energyC. greater total energyD. less magnitude of angular momentum, about the centre of the circular orbit.

Answer» Correct Answer - C
`K.E.=(GMm)/(2R), PE=-(GMm)/R`
`T.E.=-(GMm)/(2R)`
Angular momentum `mvR=msqrt(GMR)`
