Potential difference

  1. Mar 3, 2007 #1
    Hi, I would like to have some suggestion about how to do this problem:

    Given the electric field vector E=x(1-sin (phi))+ y.cos(phi)
    x and y are unit vectors.
    Calculate the potential difference between the points A(0,1) and B(1,0).
    along :

    1- Circular arc from(0,1) to (1,0)

    2-straight line connecting (0,1) and (1,0)

    thank you.
    1. The problem statement, all variables and given/known data

    2. Relevant equations

    3. The attempt at a solution

    V is the path integral of E dot dL, with a minus sign(convention).

    I have succeeded to do the first question but how to do the second one. I found the line equation( I think it can help) but then I dont know how to continue.
