**[SOLVED] Griffiths 7.3**

## Homework Statement

Two metal objects are embedded in weakly conducting meterial of conductivity of [itex]\sigma[/itex] Show that the resistance between them is related to the capacitance of the arrangement by

[tex]R=\frac{\epsilon_0}{\sigma C}[/tex]

## Homework Equations

## The Attempt at a Solution

I am not sure how sigma or epsilon_0 comes in. The only way I know how to do this problem is by getting the E-field and that is obviously not possible since they tell you nothing about the geometry.
