Question

A mass of 200kg is kept on the ground if it covers an area of 1200 cm2 calculate the pressure exerted by it

Answer 1

mass of object = 200 kg

weight = mg = 200×10 = 2000 N

Area covered = 1200 cm^2

1m^2 = 10000 cm^2

So area = 1200/10000 = 0.12 m^2

Pressure = Weight/area = 2000/0.12 = 16666.6 Pa = 16.67 kPa

Pressure exerted is 16.67 kPa
