Explanation / Answer

16)

The net force acting on the object will always be "0" is that case.

If there happens to be any net force, the object will accelerate in that particular directon as per Newton's second law and this would result in the change of velocity and thus a change in kinetic energy.

So, the net force has to be zero.
