Question

A man puts a box on a round cloth of area 0.2m2
over his head. The pressure exerted by the box
is 0.25 N/m2
. Find the force exerted by the box. If the man places the same box on another piece
of cloth of area 0.5m2
, what will be the pressure on his head now?

Answer 1

• Area=0.2m^2
• Pressure=0.25N/m^2

We know

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

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

$\\ \sf\longmapsto Force=0.25\times 0.2$

$\\ \sf\longmapsto Force=0.05N$
