Answer 2

The pressure provided by the boy is 10 kPa.

Explanation:

Force applied by the boy, F = 16 N

Area of cross section, $A=16\ cm^2=16\times 10^{-4}\ m^2$

Let P is the pressure provided by him. The force acting on an object per unit of its area is called pressure. Mathematically, it is given by :

$P=\dfrac{F}{A}\\\\P=\dfrac{16\ N}{16\times 10^{-4}\ m^2}\\\\P=10000\ Pa\\\\P=10\ kPa$

So, the pressure provided by the boy is 10 kPa.
