Find the magnitude of the electric field in the capacitor

  1. Feb 1, 2008 #1
    1. The problem statement, all variables and given/known data
    An electron entering a parallel-plate capacitor with a speed of v=5.20 x 10^-6 m/s. The electric field of the capacitor has deflected the electron downward by a distance of d=0.594cm at the point where the electron exists the capacitor.
    a)find the magnitude of the electric field in the capacitor____N/C
    b)find the speed of the electron when it exists the capacitor___m/s


    2. Relevant equations



    3. The attempt at a solution

    I have no clue how to start this problem

    What's the electric force on a charge in an electric field? Apply this to Newton's second law.

    Then think about your kinematic equations (like in projectile motion).
