Cross section of the solid cylinder and concentric Gaussian surface.
Cross section of the solid cylinder and concentric Gaussian surface.
A long, nonconducting solid cylinder of radius \(R\) carries a uniform volume charge density \(\rho\). The electric potential at the surface of the cylinder is set to zero, so \(V(R) = 0\). Which of the following expressions gives the electric potential \(V(r)\) inside the cylinder (\(r < R\)) as a function of distance \(r\) from the central axis?
