vanishing only in the region ar<<b. For r<a, the enclosed charge is since any net charge in a conductor must reside on its surface. Similarly, for , the enclosed charge is qenc =0 r>b qenc =λAA−λ=0 since the Gaussian surface encloses equal but opposite charges from both conductors. The potential difference is given by 00 ln 22 b baa r b a ...
