Question

Calculate the pressure when a force of 200 N is exerted on an area of: 

(a) 10m² 

(b) 5m²

Answer 1

Given: Force applied is given as: 200 N

Now, we know that the Pressure is the force applied perpendicular to the surface of an object per unit area. or Pressure = Force/ Area

(a) Area = 10m²

P = 200N/10m² 

or P = 20 Nm² or 20 Pascal

(b) Area = 10m2

P = 200N/5m² 

or P = 40 Nm² or 40 Pascal
