Question

find pressure when (I) area is 40m^2 and force is 400n, (II) area is 50m^2 force is 400n (III) area is 20m^2 force is 400n
​

Answer 1

i)P=F/A=400/40Pa=10Pa

ii)P=F/A=400/50Pa=8Pa

iii)P=F/A=400/20Pa=20Pa

Answer 2

Answer:

Pressure =force per unit area

Here force is 400N and area is 40m^2

P=400/40=10pascal

In 2 nd case force is 400N and area is 50m^2

P=400/50=8pascal

In 3rd case force is 400N and area is 20m^2

P=400/20=20pascal
