PHY 102 Electrostatics: Electric Charge and Coulomb's Law Objective Question

Question

What is the net electric flux through a closed Gaussian surface that encloses no net charge, even if there are charges outside the surface?
Options
A Infinite
B Proportional to the outside charges
C Zero
Correct Answer
D Negative
Correct Answer

Option C is the correct answer.

Detailed Explanation

If no charge is enclosed, every field line from an external charge that enters the surface must also exit it, resulting in a net flux of zero.

Hint

Lines entering must equal lines leaving.
