Question

A cuboidal block of mass 2kg with each side of 2cm is lying on the griund .what will the pressure exerted by the block on the ground

Answer 1

first calculate area of triangle then apply formula p =f/a
                                                                                 

Answer 2

Mass , m = 2 kg

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

Area = a² = 0. 02 × 0. 02 = 0.0004 m

Pressure = force/area
= mg/area
= 2 × 10 ÷ 0.0004
= 50000 Pa
