A comet revolves around the sun in an eliptical orbit. When it is closest to the sun at a distance d, its corresponding kinetic energy is k_(0) . If it is farthest from the sun at distance 3d then the corresponding kinetic energy will be

A star like the sun has serveral bodies moving around it at different distance. Consider that all of them are moving in circular orbits. Let r be the distance of the body from the centre of the star and let its linear velocity be upsilon , angular velocity omega , kinetic energy K , gravitational potential energy U , total energy E and angular momentum L . As the radius r of the orbit increase, determine which of the above quantities increase and which ones decrease.
