In general, there are two ways to think about the electric force: either one charge interacts with another charge or one charge interacts with the electric field that is produced by another charge. We will usually favor thinking about how charges interact with the field (rather than how charges interact with other charges) because it is through that field that the interaction occurs. These notes will introduce the general relationship between electric force and electric field and discuss the example of a positive and negative point charges (which we will call an electric dipole). | In general, there are two ways to think about the electric force: either one charge interacts with another charge or one charge interacts with the electric field that is produced by another charge.
