2. An electron moves from point i to point f, in the direction of a uniform electric field. During this motion: a. A) the work done by the field is positive and the potential energy of the electron-field system increases B) the work done by the field is negative and the potential energy of the electron- field system increases C) the work done by the field is positive and the potential energy of the electron-field system decreases D) the work done by the field is negative and the potential energy of the electron- field system decreases E) the work done by the field is positive and the potential energy of the electron-field system does not change
