Cross-sectional view of the charged rod and concentric spherical surfaces.
Cross-sectional view of the charged rod and concentric spherical surfaces.
A thin, nonconducting rod of length \(R\) carries a total positive charge \(Q\) distributed uniformly along its length. The rod is centered at the origin of a coordinate system. Three concentric spherical Gaussian surfaces \(S_1\), \(S_2\), and \(S_3\) with radii \(R\), \(2R\), and \(3R\), respectively, are centered at the origin. Let \(\Phi_1\), \(\Phi_2\), and \(\Phi_3\) represent the net electric flux through surfaces \(S_1\), \(S_2\), and \(S_3\), respectively. Which of the following correctly ranks the net electric fluxes through the three surfaces?
