Homework Help: Parallel plate capacitor book problem

  1. Sep 13, 2010 #1
    1. The problem statement, all variables and given/known data

    Two parallel plates 0.700 cm apart are equally and oppositely charged. An electron is released from rest at the surface of the negative plate and simultaneously a proton is released from rest at the surface of the positive plate. How far from the negative plate is the point at which the electron and proton pass each other?

    2. Relevant equations

    E = [tex]\lambda[/tex]/[tex]\epsilon_{0}[/tex]

    3. The attempt at a solution

    I'm not sure how to begin...

    Begin by writing the appropriate kinematics equations for each particle. One of the particles starts at zero and the other starts at 0.700 cm and moves towards zero. Can you find the acceleration of each particle?
