Question

how pointed nails can be inserted easily than blunt knife




please urgently​

Answer 1

Answer:

Because in pointed nails, the surface area is low, so the pressure exerted is high. So with a less force, the nails can go inside, whereas blunt knife has a greater surface area, so the pressure which is needed is more.

Answer 2

Answer:

A sharp knife cuts objects better because due to its very thin edge, the force of our hand falls over a sharp small area of the object producing a large pressure. ... A blunt knife has a thicker edge and does not cut the object easily.

Explanation:

so u can say that less is the area more is the pressure inserted becoz P=F/A
