Assume we have a long line of length L L, with total charge Q … WebA long straight wire has fixed negative charge with a linear charge density of magnitude 4.8 nC/m. The wire is to be enclosed by a coaxial, thin-walled, nonconducting cylindrical shell of radius 1.2 cm. The shell is to have positive charge on its outside surface with a surface charge density s that makes the net external electric field is zero.

Using this, and equation ( 1), we get. σ ( x 0, y 0, z 0) = ρ ( x 0, y 0, z 0) d A d t d A = ρ ( x 0, y 0, z 0) d t. However, since we are talking about a surface, thus the thickness being infinitesimally small, the surface charge density ( σ) must vanish.
