Question

a cubical block of mass 2kg with each side 2 cm is lying on the ground .calculate the pressure exerted by the block on the ground

Answer 1

Mass , m = 2 kg

Side of the cube, a = 2 cm = 0. 02 m

Area = a² = 0. 02 × 0. 02 = 0.0004 m

Pressure = $\frac{Force}{Area}$
= $\frac{mg}{area}$
= 2 × 10 ÷ 0.0004
= 50000 Pa
