    The electron is subject to a vertical acceleration that causes it to have a deflection of  5 \times 10^{-4} m. Write two kinematics equations for the vertical and horizontal displacements. The vertical acceleration can be found by using F = ma.
    Spoiler:

     F_{net}= ma_y
     qE= ma_y
      s_x = 0.4ct
      s_y = \frac{1}{2}a_yt^2
