    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?

    Answer:

    \[F=500000\text{ }N,\] \[P=250000\text{ }Pa,\]                \[A=?\] we know that\[A=\frac{F}{A}=\frac{500000}{2500000}{{m}^{2}}=0.2\,{{m}^{2}}\]
