(adsbygoogle = window.adsbygoogle || []).push({}); 1. The problem statement, all variables and given/known data

A telephone wire of diameter 1mm is suspended 10m above the ground. Estimate its capacitance to earth per unit length

2. Relevant equations

3. The attempt at a solution

I've tried to solve the problem by using the formula for a cylindrical capacitor and got the answer but apparently it was wrong. Instead it's supposed to be solved by the mirroing method. So now I'm lost. Help me please :)

Thx
