peripheral zero voltage simulates the field at infinity. 2) Add two point charges and a cylindrical polarization inside the field. The point charges are 0.1 mC and -0.1 mC, respectively, and the magnitude of polarization is 0.1mC/mm2. The positions of the point charges and polarization cylinder are
