1. The problem statement, all variables and given/known data

I have the following problem regarding to dielectric and potencial

Problem:

Consider 2 conductive bars parallel with a distance ādā between them (smal distance compared to the size of the bars), connected to diference of potencial Vo.The space between the bars is filed with a constant dielectric material epsilon = epsilon (z), in the way that epsilon(0)=epsilon 1. The electrostatic potencial between the 2 bars is :

where K is a constant that is determined experiamentally.

Determine the following:

1) The electrostatic potencial V(z) in the region between the bars.
2) the dependence of the constant dielectric of the variable z , to be consistent with (*)
3) The free density charge of the conductors
4) The vector of polarization P and the polarization charges of the dielectric.
