Question

What is the force needed to produce of 1 pa over a square area of side 2m.

Answer 1

given

pressure = 4 pa
side  of the square= 2m
area of the square = 2^2 = 4m^2

now we know

pressure = force /area

force = pressure x area

force = (1 x 4)N = 4 N

Answer 2

hi friend,. pressure = force /area of square which means.....force =pressure ×area of square
now .area of square =a^2=2^2=4




now force needed =1×4=4 pa.m^2



I hope this will help u :)
