Homework Help: Electric Field

  1. Oct 10, 2011 #1
    1. The problem statement, all variables and given/known data

    Velocity components of an electron moving between two charged paralle plates are Vx=(1.5*10^5 m/s) and Vy=(3*10^6 m/s). Electric field between the plates is E=(120 N/C) j Find
    1) Accleration of electron
    2) Velocity of electron after its x-coordinate has changed by 2 cm

    2. Relevant equations

    F(= ma) = Eq (q=1.6*10^-16)

    3. The attempt at a solution

    1) from the equation, accl. is -2.1*10^13
    2) how do i find the velocity.
