Vedclass · Answer

(A) The only force acting on the satellite is the gravitational force exerted by the earth. According to Newton's law of gravitation,this force is always directed towards the centre of the earth. Since $F = ma$,the acceleration $a$ of the satellite is also always directed towards the centre of the earth. Angular momentum is conserved because the gravitational torque about the centre of the earth is zero. Total mechanical energy remains constant in an elliptical orbit. Linear momentum changes in both magnitude and direction due to the varying speed and path of the satellite.

$A$ 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.
