Question

A boy weighing 60 kgf stands on platform of dimensions $2.5\times 0.5cm$. What pressure in Pascal does he exert?

Answer 1

Step 1, Given data

Weight of the boy =60 kgf = 600 N

Dimension of the platform = $2.5cm\times 0.5cm$

So, we can write Area = $1.25{cm}^2=1.25\times {10}^{-4}{m}^2$

Step 2, Finding the pressure

We know,

Pressure exerted is given as

$Pressure=\frac{Force}{Area}=\frac{Weight}{Area}$

Putting all the values

$Pressure=\frac{600}{1.25\times {10}^{-4}}=4.8\times {10}^6$ N/$m^2$ or Pascal.
