Version 001 – HW06 – gavrin – (25111) 1 This print-out should have 13 questions. Multiple-choice questions may continue on the next column or page – find all choices before answering. ChargedCylindricalShell 001(part1of2)10.0points A cylindrical shell of radius 8 . 1 cm and length 248 cm has its charge density uniformly dis- tributed on its surface. The electric field intensity at a point 22 . 9 cm radially outward from its axis (measured from the midpoint of the shell ) is 36400 N / C. Given: k e = 8 . 99 × 10 9 N · m 2 / C 2 . What is the net charge on the shell? Correct answer: 1 . 14974 × 10 6 C. 002(part2of2)10.0points What is the electric field at a point 5 . 85 cm from the axis? Correct answer: 0 N / C. ChargeandConcentricSpheres 003 10.0points A charge of 2 pC is uniformly distributed throughout the volume between concentric spherical surfaces having radii of 1 . 4 cm and 3 . 4 cm. Let: k e = 8 . 98755 × 10 9 N · m 2 / C 2 . What is the magnitude of the electric field 2 . 3 cm from the center of the surfaces?

    As a current student on this bumpy collegiate pathway, I stumbled upon Course Hero, where I can find study resources for nearly all my courses, get online help from tutors 24/7, and even share my old projects, papers, and lecture notes with other students.

    I cannot even describe how much Course Hero helped me this summer. It’s truly become something I can always rely on and help me. In the end, I was not only able to survive summer classes, but I was able to thrive thanks to Course Hero.

    The ability to access any university’s resources through Course Hero proved invaluable in my case. I was behind on Tulane coursework and actually used UCLA’s materials to help me move forward and get everything together on time.
