Question

Force exerted by a truck is 500000 N and the pressure on the ground is 2500000 Pa. Calculate the area of contact of tyres with ground?

• A. $0.1m^2$
• B. $0.2m^2$
• C. $0.3m^2$
• D. $0.4m^2$

Answer 1

The correct option is B $0.2m^2$

Force $\left(F\right)=500000N$
$Pressure=250000Pa,Area\left(A\right)=?$
$A=\frac{F}{P}=\frac{500000}{2500000}{m}^2=0.2m^2$.
