NEET Physics Electric Flux Assertion Reason Question
Assertion (A): The electric flux through a closed surface is zero if the net charge enclosed by the surface is zero.
Reason (R): The electric field lines do not pass through the surface if the charge inside is zero.
Both A and R are true, and R is the correct explanation of A.
Both A and R are true, but R is not the correct explanation of A.
A is true but R is false.
A is false but R is true.
Correct Answer
Detailed Explanation
The assertion is true based on Gauss's law, which states that the net electric flux through a closed surface is proportional to the charge enclosed. However, the reason is false because electric field lines can still pass through the surface but the net number entering and leaving is equal if the net enclosed charge is zero.
