Question
Transcribed Image Text:A very long cylinder it's length L and radius R it has a uniform bulk
density charge and equal d prove that field strength inside and outside
the cylinder
E = dR? + 2€r
r>R
E = dr +2€
r<R
Since r is the distance from the cylinder axis.
In the event that the charge is distributed along the cylinder in which
their longitudinal density (Linda ) Find the relationship between ( Linda
, density ) then use the first relationship to find the field strength outside
the cylinder in signify ( Linda) .
