Multiple-choice questions may continue on the next column or page – find all choices before answering. 001 (part 1 of 2) 10.0 points A long coaxial cable consists of an inner cylin- drical conductor with radius R 1 and an outer cylindrical conductor shell with inner radius R 2 and outer radius R 3 as shown. The ca- ble extends out perpendicular to the plane shown. The charge on the inner conductor per unit length along the cable is λ and the corresponding charge on the outer conductor per unit length is- λ (same in magnitudes but with opposite signs) and λ > 0. Q R 1 R 2 R 3 b- Q Find the magnitude of the electric field at the point a distance r 1 from the axis of the inner conductor, where R 1 < r 1 < R 2 . 1. E = λR 1 4 π ǫ r 1 2 2. E = λ 2 π ǫ R 1 3. None of these. 4. E = λR 1 3 π ǫ r 1 2 5. E = 0 6. E = λ 2 π ǫ r 1 7. E = λ √ 2 π ǫ r 1 8. E = λ 2 R 1 4 π ǫ r 1 2 9. E = 2 λ √ 3 π ǫ r 1 10. E = λ √ 3 π ǫ r 1 002 (part 2 of 2) 10.0 points For a 100 m length of coaxial cable with...
