Electric fields between parallel plates

  1. Jan 18, 2016 #1
    1. The problem statement, all variables and given/known data
    Two large parallel plates are 0.8 m apart and generate an electric field of 12 N/C between them.
    1. At 0, 1/4, 1/2, 3/4, and full distance (0.8m), how much kinetic energy does a +0.25 C charge gain as it passes through each location?

    2. Relevant equations
    V = PE/q

    3. The attempt at a solution
    I found the voltages of each distance with the equation E=Vd solving for V. Then, I found the PE(electrical) using PE = Vq where q = +0.25 C. How do I find the Kinetic Energy?

    That's poorly worded. It doesn't gain energy as it passes through a location, it gains it as it advances from one to the next.
    When it goes from the 0 to the 1/4 location, how much PE does it lose? What becomes of that PE, assuming no force to hinder it?
