Two very large, nonconducting plastic sheets, each 10.0 cmthick, carry uniform charge densities σ1,σ2,σ3and σ4 on theirsurfaces, as shown in the following figure(Figure 1). These surfacecharge densities have the values σ1 = -5.50 μC/m2 , σ2=5.00μC/m2,σ3= 1.60 μC/m2 , and σ4=4.00μC/m2. Use Gauss's law to find themagnitude and direction of the electric field at the followingpoints, far from the edges of these sheets.

What is the magnitude of the electric field at point A, 5.00 cmfrom the left face of the left-hand sheet?

Express your answer to three significant figures and include theappropriate units.
