Question
Which of the following is NOT correct about Gauss's law? I. The net charge q_enc is the algebraic sum of all enclosed positive and negative charges. II. The net charge can be positive, negative or zero. III. The net charge q_enc cannot be determined. IV. The net charge is in the direction of the applied field.
Correct Answer
Option C is the correct answer.
Detailed Explanation
Statements I and II are TRUE of Gauss's law. Statement III is false (q_enc is exactly what Gauss's law lets you determine). Statement IV is nonsense - charge is a SCALAR and has no direction.
Hint
Statements I and II are TRUE of Gauss's law.
