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
S1as
ϕ1 through
S2 as
ϕ2, etc. Which of the following is necessarily false.
