    Surface charge of an elliptical tube

    The distribution along the length of the tube is uniform if we consider a very long tube. So we can calculate a linear charge density of a thin elliptic slice and simply multiply that with the length of the tube. Here is where I have a problem. How to calculate a linear charge density of an...

    Surface charge of an elliptical tube

    Thank you for your quick replay voko. Ok, I see your point. Then I did not use the right word (lost in translation). I want calculate the areal charge density of an elliptic tube if we charge it and let the charge disperse on its own. I don’t think that we get the uniform charge density.

    Surface charge of an elliptical tube

    Homework Statement An electric charge q is uniformly dispersed over a surface of elliptical tube with major and minor axis a and b. What is the surface charge density?Homework Equations The Attempt at a Solution I I know that you have to cut the tube into thin ellipses and calculate a linear...
