Question
According to the document, if a charge is located outside a closed surface, how does it contribute to the electric flux out of that surface?
Correct Answer
Option C is the correct answer.
Detailed Explanation
The document states, 'If the surface does not enclose any particular charge, such a charge does not contribute to the electric flux out of the surface. This is because the field of the charge crosses the surface equal times in and out.' (page 14, Fig. 2.10 and accompanying text).
Hint
Consider how field lines from an external charge would pass through a closed surface.
