Electric potential at center of charged rod

  1. Aug 22, 2015 #1
    1. The problem statement, all variables and given/known data
    Find potential of a uniformly charged rod of length 2a

    2. Relevant equations
    3. The attempt at a solution
    [tex]dV=\frac{kλdx}{r}, r=x[/tex]
    [tex]V=λk\int\limits_{-a}^a \frac{1}{x}\mathrm dx=0[/tex]

    Potential at point B is zero. Is this correct?

    No. Your integral doesn't exist. But even before, what is it you are integrating, and over what are you integrating ?

    As a check: it is likely that V = 0 at infinity, so it can't be 0 at pont B.
