1.Moon is experiencing a gravitational force due to earth and is revolving around the earth in a circular orbit .How much work is done by the moon.



There is no work done by the moon bcoz when an object is moving in circular motion at every point the direction of motion of object and direction of force will be perpendicular.So no work is done.
0 0 0
The work done = 0

This is because it is 'zero work' ie. the force acts perpendicular to the displacement
