Q49 of 100 Page 209

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


(a) 10m2 (b) 5m2

Given: Force applied is given as: 200N 
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
