Question

A box weighing 'F' N is placed on a wooden plank such that the area of contact between them is 2m². If the pressure exerted by the box on the plank is 500 Pa. Find 'F'.​

Answer 1

• Area=2m^2
• Pressure=500Pa
• Force=FN

We know

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

$\\ \sf\longmapsto Force=Pressure\times Area$

$\\ \sf\longmapsto FN=500\times 2$

$\\ \sf\longmapsto FN=1000N$

• Cancel Newton(N)

$\\ \sf\longmapsto F=1000$
