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 total mechanical energy of S varies periodically with time

B

The linear momentum of S remains constant in magnitude

C

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

D

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

Text Solution
