Finding surface charge density incase of coaxial cable
A long coaxial cable carries a uniform (positive) surface charge density σ1=5μC/m2. On the inner cylinder radius R1=0.8mm, and uniform surface charge density on the outer cylindrical shell (radius R2=1.4mm). The surface charge is negative and of just the right magnitude so that the cable as a whole is neutral. Find the surface charge density σ2 of the cylindrical shell of radius R2.

A long straight wire has fixed negative charge with a linear charge density of magnitude 3.2 nC/m. The wire is to be enclosed by a coaxial, thin-walled, nonconducting cylindrical shell of radius 2.0 cm. The shell is to have positive charge on its outside surface with a surface charge density σ that makes the net external electric field is zero. Calculate σ.
