Question

Calculate the force which which is applied to an area of 4.5cmsquare to protect a a pressure a pressure of 22pa

Answer 1

force(thrust)=pressure/area
=22/4.5
force=4.88888889 N

Answer 2

GIVEN,

Area=4.5cm^2=0.045m^2, pressure=22pascal, pressure=force/area 22pa=force/0.045, force=22×0.045=0.990N,therefore, force=0.99N or 1N(approx.)
