Question

say work is done or not justify your answer the revolution of earth around the sun

Answer 1

here no work is going to be done because The gravitational force is conservative, which implies that the work done by such a force on an object passing from A to B is path-independent. In the model where the Sun alone acts on the Earth, the fact that the Earth completes a closed orbit automatically implies that the net work done on it by the Sun is zero

Answer 2
