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

    Hey guys.
    So, I've got this question and what I tried to do.
    I found the electric field of the wire using Gauss law but then I got stuck.
    I don't think I understood the problem correctly.
    Any idea about what should I do guys?

    Thanks.

    2. Relevant equations
