Three point charges and a closed surface S.
Three point charges and a closed surface S.
Three point charges are held fixed in a line: Charge 1 has charge \(+2q\), Charge 2 has charge \(-q\), and Charge 3 has charge \(+q\). A closed surface \(S\) encloses Charge 1 and Charge 2, but leaves Charge 3 outside.

Which choice correctly pairs the net electric flux \(\Phi_E\) through surface \(S\) with the net flow of electric field lines across surface \(S\)?
