Can someone give me examples of the following two situations and clarify each situation?
-An object is stationary but the point of application of the force moves on the object.
-An object moves in such a way that the point of application of the force remains fixed.
Moreover, what can one say about the work done by the force on the object in each case?

This sure looks like a homework assignment. Is it?

If an object is stationary, the net force on the object is zero. At a minimum, you'd need a pair of equal but opposing forces to have a force on a stationary object, but the problem statement seems to imply there's only a single force, so it's not clear what the point of the first problem statement is.
