Question

A boy is weighing 80kgf stands on a platform of dimensions 2.5cm × 0.5cm . what pressure in pascal does he exert?​

Answer 1

• Force=80kgf

Convert to Newton

$\\ \sf\longmapsto 80\times 9.8$

$\\ \sf\longmapsto 784N$

Area of platform

$\\ \sf\longmapsto 2.5\times 0.5=1.25cm^2=0.0001m^2$

We know

$\boxed{\sf Pressure=\dfrac{Force}{Area}}$

$\\ \sf\longmapsto Pressure=\dfrac{784}{0.0001}$

$\\ \sf\longmapsto Pressure=7840000Pa$
