An infinite line charge of uniform electric charge density l lies along

An infinite line charge of uniform electric charge density l lies along the axis of an electrically conducting infinite cylindrical shell of radius At time t = 0, the space inside the cylinder is filled with a material of permittivity e and electrical conductivity s. The electrical conduction in the material follows Ohm’s law. Which oneof the following graphs best describes the subsequentvariation of the magnitudeof current density j(t) at any point in the material?
