A. Which of these statements about a dipole are correct? Select all that are true. I: The electric field at any location in space, due to a dipole, is the vector sum of the electric field due to the positive charge and the electric field due to the negative charge. II: At a distance d from a dipole, where d >> s (the separation between the charges), the magnitude of the electric field due to the dipole is proportional to III: At a distance d from a dipole, where d >> s (the separation between the charges), the magnitude of the electric field due to the dipole is proportional to 1 • IV: A dipole consists of two particles whose charges are equal in magnitude but opposite in sign. V: The net electric field due to a dipole is zero, since the contribution of the negative charge cancels out the contribution of the positive charge. A. I B. II C. III D. IV E. V B. A dipole is centered at the origin, and is composed of particles with charges +e and -e, separated by a distance 1.2 nm along the y-axis.
