Studying Electron moving into uniform electric field?

  1. Dec 31, 2016 #1
    Hi ,

    I am trying to understand the outcome of below scenario.

    An electron moving with a constant velocity v along x-axis enters a uniform electric field applied along Y-axis. Then the electron moves

    1. with uniform acceleration along y-axis
    2. without any acceleration along y-axis
    3. in a trajectory represented as y=ax^2
    4. in a trajectory represented as y=ax

    I am speculating the answer is 3rd option. However, I am not sure why.

    Could you please help me understand what is the answer and some explanation would be helpful?

    Many Thanks
