Explanation:
We know that Pressure is inversely proportional to area.The nail can penetrate the wood because it is sharp, applying high pressure to the surface area it contacts. The nail's head is relatively much wider, so it will not penetrate your hand as easily as the sharp end, but it is clearly not engineered to be pushed in by hand.

Answer:
We know that Pressure is inversely proportional to area. So, smaller area will exert more pressure, thus a sharp nail has small area that comes in contact with the object, so more pressure can be applied on the object. ... Therefore it becomes easy to penetratea sharp nail easily through wood than a blunt nail.
