Unformatted text preview: The circle lies in the xy plane with its center at the origin. What is, Î» , the charge/length on the circle. What is E (d e z ) in terms of Î» . Compare this result to the continuous uniform charge/length, Î» on the circle. 3) In class the following problem was considered. A right circular cylindrical volume of radius R and length L with axis along z and one end at the origin carried a uniform volume charge density Ï . We found E ([L + D] e z ). Now suppose a similar volume with charge densityÏ was located in the regionL â‰¤ z â‰¤ 0. What is the E ([L + D] e z ) from both charge distributions? When D >> R and D >> L what is the ï¬eld? 4) JDJ 13 5) JDJ 15 1...
