Question

The pressure exerted on the floor by a Cylinder of area of cross section 100 $m{m}^2$ is 1000 Pa. What is the thrust applied by the cylinder on the floor?

Answer 1

We know,

Pressure = Force/Area ----------- i
Given,
Area = 100 mm²
= 100 x (1/1000000) m²
= 0.0001 m²

From i,
Force = Pressure x Area

= 1000 x 0.0001 = 0.1 N
