Question

Calculate the pressure exerted by a block of 45N if surface area in contact is 0.5m2

Answer 1

Pressure = Force/Area
force = 45N
Area = 0.5m²
pressure = 45/0.5
= 450/5
= 90Nm^-2

Answer 2

Hi there !!

Force = F = 45 N

Area = 0.5 m²


Thrust = Force = 45 N


Pressure = $\frac{Thrust}{Area}$

= $\frac{45}{0.5}$

= 90 Pa
