Question

Why is it easier to dive a pointed nail into the wall instead of a blunt nail?

Answer 1

Answer:

Explanation:

A blunt nail has more surface area at the tip. So the thrust(force) on the blunt nail will exert less pressure on the wall as P is inversely proportional to area . A sharp nail covers less area on the wall and that is why the thrust on it causes more pressure so the sharp nail penetrates through the wall
