Question

A nail has an area of ​2 cm2​ ​ at the broad end and 1/100 ​cm2​ ​ at the pointed end. If a force of 700
N is applied on the broad end, what is the pressure exerted on the wall?

Answer 1

Answer:

The pressure exerted on the wall is "7 Megapascal" or "7x10^6 pascal".

Explanation:

Data:-

Broad End of nail = A = 2cm^2

Pointed end of nail = a = 1/100 cm^2 = 1x10^-4 meter

Pressure exerted on the wall = P = ?

Solution:-

As the pointed end of the nail is pressed against the wall. Therefore, we use the area of pointed end of nail in the formula of pressure.

Pressure is given by folllowing equation:

         Pressure exerted = Force applied / Effected area.

              P = F / a.

              P = 700 / 1X10^-4

         Pressure exerted on wall = P = 7 Megapascals.
