Determine the polarizability of a wire segment.
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
ħq. 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.
