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.

A

the linear momentum of S remains constant in magnitude.

B

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

C

the angular momentum of S about the centre of the earth changes in direction, but its magnitude remains constant.

D

the total mechanical energy of S varies periodically with time.

Text Solution

Verified by Experts

The correct Answer is:
B
The gravitational force on the satellite S acts towards the centre of the earth, so the acceleration of the satellite S is always directed towards the centre of the earth.
