Question

A rod containing charge +Q is brought near an initially uncharged isolated conducting rod as shown. Regions with total surface charge +Q and -Q are induced in the conductor as shown in the figure. The only regions where the net charge in this configuration is non-zero are indicated by the " + " and " - " signs. Let us denote the total flux of electric field outward through closed surface $S_{1}$ as $ϕ_{1}$ , through $S_{2}$ as $ϕ_{2}$ , etc. Which of the following is necessarily false.
