(a) In which direction does the electric field due to the bound surface charge point at a location above the top surface in Figure 26.13c?

(b) In which direction does it point at a location between the top and bottom surfaces?

Figure 26.13 The polarization induced on a dielectric in a parallel-plate capacitor is equivalent to two thin sheets carrying opposite charge. (a) Dielectric sandwiched between capacitor plates capacitor plate -9 dielectric capacitor plate (b) positive bound surface charge negative bound surface charge +4 (c) Polarization induced on dielectric is equivalent to pair of charged sheets.
