Question

give one example for the following case: Neither force is applied nor is work done​

Answer 1

Answer:

circular orbit

Explanation:

There are many important examples of forces which do no work because they act perpendicular to the motion. For circular motion, the centripetal force always acts at right angles to the motion. It changes the direction of the motion, but it does no work on the object. This can be applied to any circular orbit.
