A satellite S is moving in an elliptical orbit around the earth. The mass of the satellite is very small compared to the mass of the earth.
- The acceleration of S is always directed towards the centre of the earth.
- The angular momentum of S about the centre of the earth changes in direction, but its magnitude remains constant.
- The total mechanical energy of S varies periodically with time.
- The linear momentum of S remains constant in magnitude.
Answer
(A) The acceleration of S is always directed towards the centre of the earth.
