Once again we're including a quiz question that reviews material you will encounter in the cumulative portion of Midterm 3. The particular topics we're focusing on are (1) the relationship between electric fields and electric forces, (2) the relationship between electrical potential energy and electrical potential, and (3) the relationship between electric fields and electric potentials. So think back to what you already know to answer the following question:
Points A through D form a square in a uniform E-field, as show. The horizontal sides of the square (C to D and A to B) are parallel with the field and the vertical sides of the square (A to D and B to C) are perpendicular to the field. A negatively charged particle begins at point D, moves to E, then to C, then to B, and ends at A.
Which of the following is TRUE about its trip? You may select more than one statement.
The particle gains electrical potential energy from B to A.
The particle passes through a negative potential difference from C to B.
The particle gains electrical potential energy from E to C.
The particle passes through a positive potential difference from D to E.
The particle passes through a negative potential difference from B to A.
The particle gains electrical potential energy from C to B.
The particle loses electrical potential energy from D to E.
The particle passes through a negative potential difference from E to C.
