Question

A solid weighs 300 N. Calculate the pressure exerted by the solid on a surface, if the area of contact is 2 m 2 .

Answer 1

Step-by-step explanation:

we know that

pressure= force/area

the mass of solid is 30kg

weight is 300N

weight=mg=30×10=300N

that is the force

area = 2m²

so

pressure=300/2=150N/m²
