Answer:
When
a satellite moves around the Earth in a circular path, then the force of gravity
acts on it directed towards the centre. The motion of the satellite is in the
horizontal plane. Therefore, the force of gravity of Earth on the satellite and
the direction of motion of satellite are perpendicular to each other. Therefore,
net work done = Fs cos 90° = 0. That is, the work done by the force of gravity
on a satellite moving around the Earth is zero.
