Question

I want answer these questions.

1. what is the force needed to produce a pressure of 1 pascalover a square area of side 2m?

2. Over what area should a force of 100N act to produce a pressure of 500 pascal?

3. A force of 25N acts on an area of 25 c.m.square . Calculate the pressure produced.

Answer 1

pressure= force/ Area

1) 1= force/4m^2

=> force= 4N

2) 500= 1000N/Area

=> Area= 1000/500= 2m^2

3) pressure= 25/25= 1 Pascal.
