Homework Help: Determine the polarizability of a wire segment.

  1. Sep 15, 2012 #1
    1. The problem statement, all variables and given/known data

    The center of the spherical metal ball of
    radius R, carrying a negative charge -Q, is
    located a distance r from the center of a short,
    thin, neutral copper wire of length L. The
    induced charges at the two ends of the wire is
    ±q. Determine the polarizability of the wire
    segment which has a length L = 0.0105 m.

    2. Relevant equations

    E = k*2qL/r^3
    F = qE
    E(dipole) = k*2*alpha*E(sphere)/r^3

    3. The attempt at a solution

    I am given so many variables that I could not find a way to get any values from these equations.
