Question

Figure 23-55 shows, in cross section, three infinitely large nonconducting sheets on which charge is uniformly spread. The surface charge densities are ?1 = 1.39 ?C/m2, ?2 = 2.18 ?C/m2, and ?3 = -3.06 ?C/m2, and distance L = 0.950 cm. In N/C, what are the (a) x and (b) y components of the net electric field at point P?

Explanation / Answer

a) Ex = 0 N/C b) Ey = (1.39+2.28-3.06)/(2*8.854*10^-12) = 3.44*10^4 N/C
