Pressure Exerted by Sharp Needle vs. Blunt Needle
Pressure is defined as the force applied per unit area. When comparing the pressure exerted by a sharp needle and a blunt needle on a surface, the key factor to consider is the surface area in contact with the object.
Sharp Needle
- A sharp needle has a very small surface area in contact with the object.
- As the surface area is small, the force applied by the sharp needle is concentrated over a small area.
- This results in a higher pressure being exerted by the sharp needle on the surface.
Blunt Needle
- A blunt needle has a larger surface area in contact with the object.
- The force applied by the blunt needle is distributed over a larger area.
- Due to the larger surface area, the pressure exerted by the blunt needle on the surface is lower compared to that of a sharp needle.
Therefore, the pressure exerted by a sharp needle is more than the pressure exerted by a blunt needle. This is because the force is concentrated over a smaller area in the case of a sharp needle, resulting in higher pressure.

Pressure is defined as P = Force applied/Area
So the pressure applied is inversely proportional to the area to which it is applied.
Since in a sharp needle, surface area on which the force is applied, is less than that for a blunt needle.
Hence, pressure exerted by a sharp needle is more than blunt needle.
