Flux through cylinder

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

    Hey guys.

    I have this question:

    http://img122.imageshack.us/img122/2936/84391716.jpg [Broken]

    I think that the flux through the top and bottom is zero and that because A does not have a component in the z axis direction.
    So all that got left is the lateral area.
    Well, I get 0 and I don't know why. I'm suppose to get 120, I obviously have a mistake and I don't know where.
    Can I please have some help?


    2. Relevant equations

    3. The attempt at a solution

    The normal vector to your cylinder certainly isn't (1,0,0), is it?
