what is the work done by the force of gravity on a satellite moving around the earth justify your answer

satellite moving around the earth is pulled towards the centre by the centripetal force acting normally at any point of its journey around the orbit.

hence, work done by the force of gravity on a satellite is 0 because centripetal force is perpendicular to the displacement.
