Statement of a problem № 41624


The Coaxial Cable A long coaxial cable consists of an inner cylindrical conductor with radius a and an outer coaxial cylinder with inner radius b and outer radius c. The outer cylinder is mounted on insulating supports and has DO net charge. The inner cylinder has a uniform positive charge per unit length λ. Calculate the electric field (a) At any point between the cylinders a distance r from the axis and (b) At any point outside the outer cylinder. (c) Graph the magnitude of the electric field as a function of the distance r from the axis of the cable, from r = 0 to r = 2c. (d) Find the charge per unit length on the inner surface and on the outer surface of the outer cylinder.
