An Electron Moves from Point I to Point F, in the Direction

Multiple Choice

An electron moves from point i to point f, in the direction of a uniform electric field. During this motion:

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
