Question

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 earth

Options:

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

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

C . The total mechanical energy of S varies periodically with time

D . The linear momentum of S remains constant in magnitude

Answer: Option A
:
A
The satellite revolves around the earth due to gravitational force that acts towards the centre of the earth. And according to the Kepler's laws the angular momentum of the satellite reamains constant but not the linear momentum
