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 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 O E. V B. A dipole is centered at the origin, and is composed of particles with charges +e and -e, separated by a distance 0.7 nm along the y-axis. The +e charge is on the -y-axis and the -e charge is on the +y-axis. A proton is located at m. What is the net electric field at the location of the proton? ( ☐ . ☐ ☐ ) N/C C. Determine where you should place an electron (in m) so that the net force (from the dipole and the electron) on the proton will be zero. (1.0.1) m
