22.30 Two very large, nonconducting plastic sheets, ea 10.0 cm thick, carry uniform charge densities σ1, 02, 03, a σ4 on their surfaces (Fig. E22.30). These surface charge den ties have the values σ₁ = -6.00 μC/m², σ₂ = +5.00 μC/1 σ3 = +2.00 μC/m², and σ = +4.00 μC/m². Use Gauss's law find the magnitude and direction of the electric field at the follo ing points, far from the edges of these sheets: (a) point A, 5.00 from the left face of the left-hand sheet; (b) point B, 1.25 cm fr the inner surface of the right-hand sheet; (c) point C, in the mid of the right-hand sheet.
