For a satellite moving in an orbit around the earth, the ratio of kinetic energy to the magnitude of  potential energy is

The kinetic energy of a satellite moving in an orbit around the earth is given byK=12mv2=12mGMror =GMm2r……….(1)The potential energy of satellite and earth systemU=GMmr………….(2)where r is the distance of the satellite from the centre of the earthKU=GMm/2rGMm/r=12
