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 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
- the acceleration of S is always directed towards the centre of the earth
Correct Answer: Option(d)
