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. Then,

Options

  1. Athe total mechanical energy of S varies periodically with time.
  2. Bthe linear momentum of S remains constant is magnitude.
  3. Cthe acceleration of S is always directed towards the centre of the earth.
  4. Dthe angular momentum of S about the centre of the earth changes in direction, but its magnitude remains constant.

Correct answer

C. the acceleration of S is always directed towards the centre of the earth.

Step-by-step solution

The gravitation force on the satellite will be aiming toward the centre of earth so acceleration of the satellite will also be aiming toward the centre of earth.
