Is the electric force on a charged particle always in the same direction of the field? What if it is an uncharged particle? If you have an electron, with the field vectors pointing radially inward, then place a proton in the field, then yes since the proton is attracted towards the electron as well. But if you place an electron in the field, the electric force will not be in the same direction as the force, right? The same concept applies with an electric field about a stationary proton, if you have another proton, then yes, the directions of the electric force and field are the same. But if you have an electron, this is not true. Could anyone please clarify or confirm anything I have said? Thank you!
