Particle detectors and Flemming LH rule

  1. Feb 29, 2012 #1
    1. The problem statement, all variables and given/known data
    http://www.thestudentroom.co.uk/attachment.php?attachmentid=118892&d=1329155852

    (the most important aspect is the CHARGE)

    2. Relevant equations


    3. The attempt at a solution
    so we know that the first finger (using flemming LHR) is into the page
    but there are two possibilities:
    (a) current up and force left
    OR
    (b) current right and force up

    WHICH one would I use and why?
    I have never really been able to distinguish the two from each other with regards to LH rule in questions like this

    thanks
