Which of the following quantities does not depend upon the orbital radius of the satellite?

The ratio of the distances of two planets from the sun is $1.38$. The ratio of their period of revolution around the sun is

An artificial satellite of mass $m$ is moving along an elliptical path around the earth. The areal velocity of the satellite is proportional to

Kepler's second law regarding the constancy of areal velocity of a planet is a consequence of the law of conservation of

$A$ satellite is launched into a circular orbit of radius $R$ around Earth,while a second satellite is launched into an orbit of radius $1.02 R$. The percentage difference in the time periods of the two satellites is:

If $J$ is the angular momentum of a planet revolving around the Sun,what is the areal velocity of the planet?
