Question

A hammer hits a nail with the force of 50N into some wood. The area of the point of the nail is 0.02cm2.What is the pressure the nail puts on the wood?

Answer 1

Answer:

answer is we can get pressure by p=f/a in which f is force and a is area so 50×0.02 and the answe is 1pa

Answer 2

The pressure the nail puts on the wood is $2.5\times10^7N/m^2$.

Explanation:

The relationship between force, pressure and area is given as

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

Here F is the applied force on area A of an object.

Given applied force F = 50 N  into wood of area $A=0.02cm^2$.

Area in m^2,

$A=0.02cm^2=2.0\times10^-^6m^2$

Substitute the given values, we get

$P=\frac{50N}{2\times10^-^6m^2}$

$P=2.5\times10^7N/m^2$.

Thus, the pressure the nail puts on the wood is $2.5\times10^7N/m^2$.
