Question

A truck has tyres of area 5m2. It puts a pressure of 15000N/m2 on the road. What is the weight of the truck?

Answer 1

$Pressure=15×10^{3} Pa</p><p>$

$Area\:of\:tyre=5m^{2}$

$area\: of\: all(4)\: tyres=5×4=20m^{2}$

$Since,\\Pressure=\frac{Force}{Area}$

$\implies Force=Pressure×Area$

$\implies Force=15×10^{3}×20$

$\implies Force=3×{10}^{5} N$

$Force=Weight=m×g\\\\\\\underline{\boxed{\sf{Weight\:of\:the\:truck\:is\:3×{10}^{5}N }}}$
