A satellite S moving in an elliptical orbit around the earth the mass

1.	A satellite S moving in an elliptical orbit around the earth the mass of satellite is very small compared to the mass of the earth then
Answer» The acceleration of S is always directed TOWARDS centre of earth The angular momentum of S about the centre of earth changes in DIRECTION, but magnitude remains CONSTANT The TOTAL mechanical energy of S varies PERIODICALLY with time The linear momentum of S remains constant in magnitude Answer :A
