Question

A force of 200N acts on a surface of area 10cm2 normally calculate the pressure exerted on the surface

Answer 1

If p=F/S (where F is the force and S is the surface area), and if we convert 10cm^2 to 0.001m^2, then:

p=200N/0.001m^2
p=200,000Pa, or 200kPa (kilopascals)

Answer 2

The SI unit of pressure is the pascal (Pa). It is a derived unit equal to 1 newton per square meter (1 N/m²).

Your pressure is ...

... (200 N)/(10 cm²) × (100 cm/m)² = 200,000 Pa
