1.A coaxial cable consists of a long straight filament surrounded by a long coaxial cylindrical conducting shell assume charge Q is on the filament zero net charge is on the shell and the electric field is E at a particular point P midway between the filament and the inner surface of the shell next you place the cable into a uniform external field -E what is the x-component of the electric field at P then ?

(a) 0

(b) between 0 and E

(d) between 0 and -E

(e) -E

2.Consider an electric field that is uniform in direction throughout a certain volume. can it be uniform in magnitude? answer these questions

(a) assuming the volume is filled with an insulating material carrying charge described by a volume charge density and

(b) assuming the volume is empty space. state reasoning to prove your answer.
