Question

Find the pressure exerted on a floor when an iron block of weight 40 N and base area 0.25 m’ is placed on it. If one more iron block of same weight is placed above it. Find the pressure?​

Answer 1

we know that P = F/A

so, pressure of one block = 40/0.25 = 160 pascals

now, there is one block with same weight is placed over the previous one which means that the force will be double and the area will be same, hence,

(40+40)/0.25 = 320 pascals

Hope it helps

Answer 2

P = F/A

pressure of one block = 40/0.25 = 160 pascals

When there is another block of same dimensions and weights placed on one and another

(40+40)/0.25 = 320 pascals
