Is it possible that a force is acting on a body but still the work done is zero ? Explain giving one example.

Is it possible exert a force which does work on a body without changing its kinetic energy? If so, give example.

When is the work done by a force zero?

Work done by magnetic force is zero. Explain.

If the force acting on the object is not in the direction of motion then how will you consider the work done ? Explain giving example and also tell when will the work done be minimum and when it will be maximum ?
