Consider an infinitely long, hollow cylinder of radius R with a uniform surface charge density σ.
1. Find the electric field at distance r from the axis, where r < R. (Use any variable or symbol stated above along with the following as necessary: ε0.)
2. What is it for r > R? E(r>R) = ?
Sketch E as a function of r, with r going from 0 to 3R. Make sure to label your axes and include scales (i.e., there should be a labeled tick mark on the r axis at r = R, and a corresponding labeled tick on the E axis.
