Answer 2

Force of 150 N acts on surface area of 3 m².

Now, we need to calculate the pressure on the surface.

• Pressure is defined as the force per unit area.
• This means that pressure can mathematically calculated as the the magnitude of perpendicular force divided by the surface area on which it acts.
• Its SI unit is N/m² , also known as Pascal.

$P = \dfrac{F}{area}$

$\implies P = \dfrac{150}{3}$

$\implies P = 50 \: Pascal$

So, pressure acting on surface is 50 Pascal.
