2. [10] The figure below shows a long conducting cylinder of radius 6mm with a hollow core of radius 2 mm. A string runs down the center of the hollow core. There is a charge density of 1 = -2 C/m on the string. Find the electric field at the 6 points Xia, X2a, X3a, Xib, X2b, and X3b. The points are defined in cylindrical coordinates, but give the components of E in Cartesian coordinates shown in the figure. string Side View ( insulator ) with AQ air conducting cylinder VX b use E = (Ex , EyIEz) .
