A point charge \(+q\) is fixed at the center of an uncharged, thick spherical conducting shell with inner radius \(a\) and outer radius \(b\) in electrostatic equilibrium. Which of the following correctly pairs the magnitude of the electric field \(E(r_1)\) at a distance \(r_1\) from the center in the cavity (\(0 < r_1 < a\)) with the magnitude of the electric field \(E(r_2)\) at a distance \(r_2\) from the center inside the conducting material (\(a < r_2 < b\))?
