Question

A small section of an infinitely long charge distribution is shown at right. A line charge of linear charge density ?line = 1.5 nC/m is at the center. It is surrounded by an inner cylinder is made from insulating material, which has a radius of 1.5 cm, and has a volume charge density given by ?inner. The outer cylindrical shell is made of a conducting material, of inner radius 5 cm and outer radius 6 cm. The outer cylindrical shell has an overall charge per unit length given by ?outer = -2.5 nC/m. a. Suppose the inner cylinder had a uniform charge density of ?inner = 2.8

Explanation / Answer

E due to cylinder = (per unit charge cylinder) / 2*pi*eo*r (where r is from the cylinder) E due to infinite long chage = per unit charge / 2*e0
