Homework Help: Curl Operator

  1. Nov 26, 2013 #1
    1. The problem statement, all variables and given/known data
    Given a vector field
    F=-y/(x^2+y^2) i +x/(x^2 +y^2)
    Calculate the curl of it the line integral of it in a unit circle centered at O


    2. Relevant equations



    3. The attempt at a solution
    I calculated that the curl is 0 but the line integral is 2π. I don't think this field should have a zero curl as you can imagine that the field is rotating.

    Show your work. Just telling us your incorrect answers doesn't let us see where your mistakes are (if there are indeed any).

    You might want to look more carefully at the requirements for applying Stoke's theorem.
