WebConsider the expression for the surface bound charge at the bottom of the slab 2 is as follows: σ b 2 = P 2 ⋅ n ^ = P 2 = σ 3. Consider the formula for the surface bound charge at the top of the slab 2 is. σ 2 = P 2 ⋅ n ^ = − P 2 = − σ 3. Solve for the total volume for the bound charges is as follows: role="math" localid ... WebSolution The surface bound charge on the xy plane is of opposite sign to q, so the force will be attractive. (In view of Eq 4.39, there is no volume bound charge.) Let us first calculate , using and : where is the z-component of the total field inside the dielectric, at . This field is due in part to q and in part to the bound charge itself.
