    Gauss's law, cylinder of length L

    ok, now I got the following: Q=integral of /rho(1-r/R) times rdr d/phi dl Which is the answer for the question of what's the charge of the cylinder L. How to calculate it?

    Gauss's law, cylinder of length L

    This is from the test, as you can see, and everything I knew was written down...

    sorry for this R! mistake. now i am looking only for the electric potential (sigma) at the point P!
