Work and electric potential in a field

  1. Apr 22, 2009 #1
    1. The problem statement, all variables and given/known data

    if the electric field does negative work on a negative charge as the charge undergoes displacement from Position A to Position B within an electric field, then the electric potential energy

    A) is negative
    B) is positive
    C) increases
    D) decreases
    E) cannot be determined

    2. Relevant equations

    u=qed, v=qu, v=ed

    3. The attempt at a solution
    since both q and u are negative V must be positive

    Within an electric field the electric potential is always positive. As you change the position it either increases or decreases. If you move in the direction of the field it decreases.
