  1. Sep 23, 2010 #1
    1. The problem statement, all variables and given/known data

    Determine the work done in carrying a -2(micro C) charge from point p1(2,1,-1) to p2(8,2,-1) in the field E = axy + ayx

    a) along the parabola x = 2y^2
    b) Along the straight line joining p1 and p2

    2. Relevant equations

    W = F*dS = Fxdx + Fydy + Fzdz

    That's right, continue...

    Also you know that a and b better give the same answer in the end because curlE is 0 for electrostatics.
