Question

Two very large, nonconducting plastic sheets, each 10.0 cm thick, carry uniform charge densities s1, s2, s3, and s4 on their surfaces (Fig. E22.30 ).

Two very large, nonconducting plastic sheets, each 10.0 cm thick, carry uniform charge densities s1, s2, s3, and s4 on their surfaces (Fig. E22.30 ). These surface charge densities have the values σf = -6.00 μC/m2, σ2 = +5.00 μC/m2, σ3 = +2.00 μC/m2, and σ4 = +4.00 μC/m2.


Use Gauss's law to find the magnitude and direction of the electric field at the following points, far from the edges of these sheets: (a) point A, 5.00 cm from the left face of the left-hand sheet; (b) point B, 1.25 cm from the inner surface of the right-hand sheet; (c) point C, in the middle of the right-hand sheet.

Answer #1

The net electric field is the vector sum of the fields due to each of the four sheets of charge.The electric field of a larger sheet of charge is calculated as below.The field is directed away from a positive sheet and toward a negative sheet.
