a 100-meter long cylindrical wire of radius 4 meters and charge 8 nC.
a) Calculate the electric field at r = 2, r = 4, and r = 6 meters away from the center of the cylindrical wire if it is a conducting cylindrical wire and the electric flux through a cylindrical wire given by those radii.
b) Calculate the same things if it is an insulating cylindrical wire of uniform charge density.
c) Calculate the same things if it is an insulating cylindrical wire of non-uniform charge density,
