  1. Apr 10, 2012 #1
    1. The problem statement, all variables and given/known data
    see attached file

    2. Relevant equations

    3. The attempt at a solution
    ok so I get that the answer is B
    but is it because they have the same q/m ratio?

    Essentially, yes.

    You should be able to work out mathematically what the accelerations are for an equal variation in the electric field (say, E = k*Eo) given that when the field is Eo they are both motionless. Hint: find the charge on each in terms of Eo and mass.
