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 E1î 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 –Eî. What is the x component of the
electric field at P then? 1. 0 2. between 0 and E1 3. E1 4. between 0 and -E1 5. - E1
