Homework Statement
I just want to make sure I'm doing this right. okay so you have a conducting corner of angle 30 degrees. How many image charges are there, I just need to sketch it.
Homework Equations
The Attempt at a Solution
my book sucks only explaining it for a 90 degree angle but I'm betting that in order to cancel the voltage for a 30 degree angle you need more than the three in my book. my graph is 11 image charges (because the 360 degrees is broken up evenly so they will cancel out and the angles this works for are 180/n because the 360/n need an even integer for there to be no charges of the same sign right next to each other. ) so I'm getting 11 image charges radially spaced starting wtih the first charge and the next two being perpendicular with teh same distance through the corners to make them V=0 and repeating around the graph.
