5. Pressure on nail

A hammer exerts a force of 3.6 \(N\) on nail \(A\) and \(B\). The area of cross section of tip of nail \(A\) is 3  ${\mathit{mm}}^2$. While that of Nail \(B\) is 7  ${\mathit{mm}}^2$. Calculate the pressure of each nail in pascal and also choose a nail which exerts high pressure.

 

 

Answer:

The pressure on nail A is $\times {10}^{-6}$ $\mathit{Pa}$

The pressure on nail B is $\times {10}^{-6}$ $\mathit{Pa}$

The nail which exerts high pressure isnail Anail B
