| Directions: In the following questions, a statement of Assertion (A) is followed by a statement of Reason: |
| (R). Mark the correct choice as: |
| Assertion (A): Total flux through a closed surface is zero, if net charge enclosed by the surface is zero. |
| Reason (R): Gauss law is true for any closed surface, no matter what its shape or size is. |
A) Both Assertion (A) and Reason (R) are true and Reason (R) is the correct explanation of Assertion (A)
B) Both Assertion (A) and Reason (R) are true but Reason (R) is not the correct explanation of Assertion (A)
C) Assertion (A) is true but Reason (R) is false
D) Assertion (A) is false and Reason (R) is also false
Correct Answer: B
Solution :
(b) Gauss law implies that the total electric flux through a closed surface is zero if no net charge is enclosed by the surface and it is true for any closed surface, independent of its shape and size.
