A uniformly charged straight wire of radius a carries linear charge density( lambda). The wire is coated with a linear dielectric mateeerial of susceptibility and external radius b.

a. find electric field everywhere
b. Find the volume and surface bound charge densities

(The straight wire of radius a must be a conducting one as the linear charge density is given)

According to Gauss law the electric flux through a closed surface is where qi is the charge enclosed within the closed surface. The field strength at a point in the field is the flux per unit area normal to the surface.

The mathematical form of gauss theorem is given as
