Homework Help: Electric potential

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

    Hey guys.
    So I got this question in the pic and also the answer I got.
    I didn't upload the entire solution because I don't have my scanner until Sunday.
    I'm not so sure about the solution and I bet some of you have already seen this question and solved it.
    So my question is, is the answer correct?


    2. Relevant equations

    3. The attempt at a solution
