Question

A piece of wood 400N in weight and 50cm X 30cm X 20cm in size lies on 50cm X 20cm face. Calculate the pressure exerted by it.

Answer 1

Answer:-

First find area of wood.

• L=50cm
• B=20cm

$\\ \sf\longmapsto Area=LB$

$\\ \sf\longmapsto Area=50\times 20$

$\\ \sf\longmapsto Area=1000cm^2$

$\\ \sf\longmapsto Area=0.1m^2$

• Force=400N

We know that

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

$\\ \sf\longmapsto Pressure=\dfrac{400}{0.1}$

$\\ \sf\longmapsto Pressure=4000Pa$
