The textbook that the electric field due to an infinite line of charge is perpendicular to the line and has magnitude E=λ/2πϵ0rE=λ/2πϵ0r. Consider an imaginary cylinder with a radius of r = 0.155 mm and a length of l = 0.500 mm that has an infinite line of positive charge running along its axis. The charge per unit length on the line is λλlambda = 5.65 μC/mμC/m . What is the electric flux through the cylinder due to this infinite line of charge?
