Question

What force will exert a pressure of 50000 pascals on area of 0.5 m² ?

Answer 1

Pressure = 50000 Pa
Area = 0.5 m²

We know that 
P = F/A
so force will be, F = P × A
so the force is 50000 × 0.5
             = 25000

so the force applied is 25000 N 

Answer 2

Pressure = 50000 Pa
area = 0.5 m²
so, force = pressure * area
force = 50000 * 0.5
force = 25000
