9. Pressure on nail

A hammer exerts a force of 8.8 $N$ on nail $A$ and $B$. The area of cross section of tip of nail $A$ is 4  ${\mathit{mm}}^2$. While that of Nail $B$ is 6  ${\mathit{mm}}^2$. 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 Bnail A
