(a) less pressure

(b) more pressure

(c) to make it artistic

(d) none of these

Answer 2

Answer:

The end of knife is made pointed to have more pressure.

Explanation:

• Due to the reduced area of contact and increased pressure, blades have a sharper cutting edge.
• The area of the surface has an inverse relationship with the pressure.
• A sharp knife may exert more pressure on an object since there is less surface area that makes contact with it.
• Therefore, due to the limited area of the nail's tail and the ability of the nail to penetrate the wall, even a small force when applied to the nail's head will result in a big pressure.
• Knives and blades are produced to recover their sharpness as their edge wears off utilizing a variety of sharpening equipment so that the cutting ease is maintained.
• Therefore, having sharp edges on all cutting equipment is crucial.

Formula used:

$P = \frac{F}{A}$

Final answer:

With the same amount of force applied, a body with a smaller surface area will exert more pressure than a body with a larger surface area.
