agn constant ,, to half-fill a parallel-plate capacitor (Fig. 4.25). By what fraction the capacitance increased when you distribute the material as in Fig. 4.25(a)? Hc about Fig. 4.25(b)? For a given potential difference V between the plates, find D, and P, in each region, and the free and bound charge on all surfaces, for ba cases.
