Application: Potential and field between charged plates. The two plates in Figure 4.63 are very large (infinite). The dielectric between the plates is air.
(a) Calculate the electric field intensity and potential between and outside the plates.
(b) If the potential on the left plate is zero, calculate and plot the potential everywhere in space.
(c) Assume that the potential difference between the plates is increased by V. This potential is connected with its positive side to the right plate with the zero potential reference kept as in (b). How does this affect the potential outside and between the plates?
