Homework Help: Help with understanding part of an integral

  1. Sep 28, 2011 #1
    1. The problem statement, all variables and given/known data


    2. Relevant equations

    3. The attempt at a solution

    The problem i'm having with this is that I'm not sure how the integral of (1/r)dr from 0 to R is


    I've had to solve this same problem 3 other ways which i got the end answer all 3 times. This way is just a little weird for me.

    NEVER MIND, I was being stupid and forgot that r<R has a different electric field
