Question

A brick is 40 cm long 10 cm wide and 10 cm thick. It weighs 48 N and is lying on the ground. Find the pressure exerted by the brick on the ground​

Answer 1

Answer:

Explanation:

Converting the units from cm to m, we have the dimensions as-

0.32 m

0.1 m

0.1 m

Area in contact with ground = 0.32 x 0.1 = 0.032 m²

We know that, Pressure = Force/Area

                                        24/0.032     =   750 N/m²  = 500Pa
