The correct answer is Decreases the area of contact and increases the pressure exerted.

Important Points

  • The cutting edges of tools like blades, knives, etc, are provided with sharp edges to cut the things easily as the sharp edges have a small area on which the force is applied, hence more pressure is applied.
  • As we know Pressure = Force/Area
  • From the above mathematical expression, we can say that the pressure applied on a body is inversely proportional to the area on which the force is applied, the pressure exerted on a small surface area is more than the pressure exerted on the large surface area.
  • So we can conclude that equal force can exert higher pressure on a small area. This is why the cutting edges of tools like blades, knives, etc., are provided with sharp edges to cut things easily.
  • The high pressure at the end of these sharp surfaces can easily pierce through wooden, plastic, etc., surfaces.
