Partial capacitances of a system of conductors

[QUOTE="Granger, post: 6065346, member: 574395"] [h2]Homework Statement [/h2] I have a small question about the following problem. The figure represents the cross-section of a three-conductor system comprising a communications coaxial cable of length l running parallel to a conducting wall (reference conductor). Determine the partial capacitance scheme of the conductor system. [![enter image description here][1]][1] [1]: [URL]https://i.stack.imgur.com/G0l6u.png[/URL] [ATTACH=full]231502[/ATTACH] [h2]Homework Equations[/h2] 3. The Attempt at a Solution [/B] So, I had zero troubles finding out the capacitance between conductor 2 and zero and between conductor 1 and 2. $$ C_{20} = \frac{2 \pi \epsilon_0 l}{\ln (\frac{d}{r_2} + \sqrt{(\frac{d}{r_2})^2 -1})}$$ $$ C_{12} = \frac{2 \pi \epsilon l}{\ln (\frac{r_2}{r_1})}$$ However I'm having trouble understanding why $$ C_{10} = 0 $$. My guess is that somehow conductor 2 acts as an electric shield between conductor 1 and conductor zero, so that the electric field due to conductor 1 is not "felt" by conductor zero. However I'm not sure if this is correct and would like some more insight about this. Can someone help me? [/QUOTE]
