    Struggling with Linear Algebra? Need more practice problems and answers?

    I don't know if it is the subj or my prof :cry: but I am having a hard time grasping Linear Algebra. We are working on vector spaces - subspaces, basis & dimension, nullspace...etc. The text we have is LINEAR ALGEBRA WITH APPLICATIONS 7E by Steven J. Leon. I don't think there are enough...

    Volume Charge Density in a long Cylinder

    No No No! :smile: I've been to hyperphysics lots - the Gaussian surface is a cylinder within another cylinder. All of the examples I have seen the cylinder is used through a plane or around another cylinder. The Charged Cylinder is of radius R and the Gaussian surface is radius r r < R...

    Volume Charge Density in a long Cylinder

    Thanks, but I've been there - the gaussian surface is always shown outside the original cylinder, that is why I am confused... :confused:

    Can Volume and Linear Charge Densities Be Interchanged in Calculations?

    OK, I may be out of my league here so feel free to let me know (in a nice way please) but conceptually & every other way I can come up with, I am trying to put together volume charge density, linear charge density and surface charge density ... for example in my text it says that in terms of a...

    Volume Charge Density in a long Cylinder

    [FONT="Arial"]I am never sure if I am on the right track when answering my homework problems. Anyway the problem involves a long solid cylinder of radius R and uniform charge distribution throughout its volume. We are supposed to choose a cylindrical gaussian surface of radius r and length L...
