Homework Help: Calc-Physics 212: Charge Distribution Geometry of a Circle

  1. Apr 12, 2012 #1
    1. The problem statement, all variables and given/known data

    Hey guys. As you can see, there are 5 questions to answer regarding this question. I'm working through it and need some help regarding a few of the questions.

    I have A.) The electric potential at the center of the circle is Zero.

    B.) The value of the electric potential anywhere inside the circle must also be zero, since the test charge anywhere inside would be zero.

    C.) Not sure of what to write for the expression of electrical potential at any point OUTSIDE the circle.

    D.) Same, not sure how I "draw a plot"

    E.) The relationship between the fields and potential are inverse of one another, correct?

    2. Relevant equations

    3. The attempt at a solution

    Thank you for being kind on my first post, made it through Calc-Based Physics 1 without any issues, but the teacher has been absent literally 4 class days and we're all trying to teach ourselves Physics 2, which has been much tougher material IMO.
