Question

a force of 200 N acts on an area of 0.02 metre square . Find the pressure in Pascals

Answer 1

pressure=force/area
p=200/0.02=10000pascal

Answer 2

Given :-

Force = 200 N

Radius = 0.02 m.sq

Soution :-

Let us find area :- 

Area = π×r² = \frac{22}{7}722  × 0.02 = 0.001256m.sq0.001256m.sq 

⇒ Now let us use the pressure formula :-

Pressure = \frac{Force}{area}Pressure=areaForce 

                     = \frac{200}{0.001256}0.001256200 

= 159235.67159235.67 Pa
