Homework Help: Angle made by electric field lines

  1. Aug 13, 2009 #1
    1. The problem statement, all variables and given/known data
    an electric field line emerges from a positive point charge +q1 at an angle x to the straight line joining it to a negative charge -q2.at what angle y will the field line enter the charge -q2?
    2. Relevant equations



    3. The attempt at a solution
    sin(y/2)=sin(x/2)(q1/q2)^1/2

    Sorry, I was assuming q1 and q2 are equal, in which case the answer is obvious from symmetry. But it appears that that are NOT equal and I don't know how to deal with that.
