Question

a brick is 20 cm long and 10 cm wide. it weights 12 N and is lying on ground. What is the are of surface of contact.​

Answer 1

Answer:

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

                                         16/0.032     =   500 N/m²  = 500Pa
