Question:

Suppose the field inside a large piece of dielectric is E0, so that the electric displacement is D0 = ?0E0 + P.?

(a) Now a small spherical cavity (Fig. 4.19a) is hollowed out of the material. Find the field at the center of the cavity in terms of E 0 and P. Also find the displacement at the center of the cavity in terms of D0 and P.?

(b) Do the same for a long needle-shaped cavity running parallel to P (Fig. 4.19b).

(c) Do the same for a thin wafer-shaped cavity perpendicular to P (Fig. 4.19c).
