Vector Calculus II: Flux Integrals

  1. May 6, 2010 #1
    1. The problem statement, all variables and given/known data


    F = 2i + 3j through a disk of radius 5 in the plane y = 2 oriented in the direction of increasing y.
    Calculate the flux of the vector field through the surface.


    2. Relevant equations



    3. The attempt at a solution

    I know that I need to calculate the area vector of the surface and then dot that with F, However, I'm in a bit of a brain slump and can't figure out how to calculate the Area Vector.

    Well, in the simple case of a planar (flat) area, the area vector is the unit normal multiplied by the usual area element in that plane.

    Yes. Shortly after the post, I was able to solve this problem. Anyways, thank you for your help.
