Question

If a boy applies a force of 8 N on an area of 1/100 m2, what will be the pressure produced by him?

Answer 1

Answer:

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

Answer 2

The pressure provided by the boy is 10kPa.

explanation:-

Force applied by the boy , F = 16 N

$\sf \colorbox{gold}{{Area of cross section , }}$

$A = 16cm^{2}$

$= 16 \times {10}^{ - 4} \: {m}^{2}$

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

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

$P = \frac{16N}{16 \times {10}^{ - 4} m^{2} }$

$P = 10000 \: Pa$

$P = 10kPa$

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