Homework Help: Motion of a charged partcile in eletric fields help

  1. May 28, 2005 #1
    I was completing some homework when I came stuck on a question. I have no idea which forumla to use. The information I've been given is : An eletron, initally at rest, accelerated by a uniform field of 10^6 NC^-1 (By the way, ^ represents to the power of).
    The question is "What is the acceleration of the electron"
    Now, im not looking for answers but which forumla to use.

    This would be of much help, thank you.

    Use the information given to find the force and Newton's laws will take care of the rest.

    Yikes, sorry for wasting your time, I just realised that and how easy it was. Sorry.

    Just another quick question ~ For the force I was going to use : F=Eq but for E it is E=/\V / D
    And I haven't been given a distance between the two plates.

    And to work out acceleration I was going to use a=Eq/m but I need to work out E.

    They GIVE you E. accelerated by a uniform field of 10^6 NC^-1
