Potential difference in an electron

  1. Jan 24, 2008 #1
    1. The problem statement, all variables and given/known data

    An electron acquires 3.01e-16 J of kinetic energy when it is accelerated by an electric field from plate A to plate B. What is the potential difference between the plates?

    2. Relevant equations

    - (Wba / q ) = V

    3. The attempt at a solution

    - (3.01e-16 / 1.6e-19) = V
    V = -1881.25

    What does the product of the charge of the electron and the pd of the plates give you?

    would those give me the velocity between the two plates?

    Why do you need the velocity for?
