State Gauss' theorem in electrostatics. Using this theorem, derive an expression for the electric intensity due to an infinitely long, straight wire of linear charge density ʎ Cm-1 .
Dear Student,
Gauss's theorem:
According to Gauss's theorem,the total electric flux over the closed surface S or can say that the surface integral of electrostatic field over S enclosing a volume V in vacuum is
times the total charge Q contained inside the closed surface S.
