Question

A box weighing 2 kg exerts a force of 20 N on the ground. The box covers an area of 2 m² on the ground. The pressure exerted by the box on the ground is:
(a) 40 N/m²
(b) 80 N/m²
(c) 10 N/m²
(d) 200 N/m²

Open in App

Solution

(c) 10 N/m²

Force exerted by the box = 20 N
Area covered by the box on the ground = 2 m²
Pressure exerted by the box on the ground = Pressure = Force/Area

$Pressure = \frac{20 N}{2 m^{2}} = 10 N / m^{2}$
