Soft sphere dissimilar

Consider the electrostatic interaction between two dissimilar spherical soft spheres 1 and 2 (Fig. 15.3). We denote by and the thicknesses of the surface charge layers of spheres 1 and 2, respectively. Let the radius of the core of soft sphere 1 be a and that for sphere 2 be a. We imagine that each surface layer is uniformly charged. Let Zi and N, respectively, be the valence and the density of fixed-charge layer of sphere 1 and Z2 and N2 for sphere 2.
