Question

The sharp nails are easy to fix than a blunt nail because it has
(A) Less area
(B) Less volume
(C) More volume
(D) None of these

Answer 1

Hint:The nail is the small piece made from the metal that has several uses like joining the two woods together, hanging the picture etc. In this nail, one side of the nail is sharp and the other side is large enough for the purpose of the holding.

Complete step by step solution:
We know that the pressure is the force acting on a unit area. Hence the pressure is inversely proportional to each other. If the force is applied to the larger area its pressure is less and if the same force acts on a very small area then its pressure is greater.
$\text{pressure}={\displaystyle \frac{\text{Force}}{\text{Area}}}$

The sharp nails are very sharp at the point of the inserting. Hence they possess very small areas and thus the pressure will be maximum. But the blunt nails have larger surface area when compared to the sharp nails and hence they have very less pressure of the same force. And hence the sharp nails are easier to fix than those of the blunt nails.

Thus the option (A) is correct.

Note:The standard unit of the pressure is $N{m}^{-2}$. The other example of the pressure is, when the man lies over the mattress, it remains the same but when the same person stands at a particular area in a mattress then it will sink more at that place.
