Which of these statements about a dipole are correct? Select all that are true. [x] [x] 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 [x] [x] A dipole consists of two particles whose charges are equal in magnitude but opposite in sign. [_] [_] 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 [_] [_] 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.
