A long tube charge with charged with uniform spatial density [tex]\rho[/tex].
The inner radius of the tube is: a
The outer radius of the tube is: b
Need to find the electric field in: a<r<b
My approach is Gauss:
E*S=4 [tex]\pi[/tex] kq
The S is the Gaussean Surface it should be 2 [tex]\pi[/tex] r^2 ??
and q should be [tex]\rho[/tex]*(r^2-a^2)??
