							Yes normal reaction can do workSuppose a block is kept on an inclined plane Now if the plane is pushed the block is also displaced Now the forces acting on the body are its weight and the normal due to the inclined surface Here displaced is not perpendicular to the normal and thus work done is non zero

Normal force is actually a contact force moreover displacement in the direction of normal force applied means that contact is lost. So there won’t be any work.
Hope you got it..

yes,when the displacement is zero ,work done =0 .so ,even if u have cos 90 degrees =1 ,S=0. So,w=f.s cos 90=f.s;if s=0,work done =0.

							Yes it`s possible, if you carry any box without changing its height from ground then wherever you go work done by gravity is always 0
