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. d. Suppose the insulator in the inner shell was defective, and some of the charge caused it to become non-uniform (but still cylindrically symmetric

Explanation / Answer

The electric field from line charge to the insulator will not be affected the charge contained there will stll be the same.

The electric field outside the outer cylinder will also not be affected due to the same reason.

The electric field will be affected in the insulator since the distribution there has changed.
