If net charge enclosed by a Gaussian sur...

If net charge enclosed by a Gaussian surface is zero, then
Assertion :- ` vecE ` at any point on Gaussian surface is 0.
Reason :- No net charge is enclosed by Gaussian surface, so E = 0

A

If both Assertion & Reason are True & the Reason is a correct explanation of the Assertion.

B

If both Assertion & Reason are True but Reason is not a correct explanation of the Assertion.

C

If Assertion is True but the Reason is False.

D

If both Assertion & Reason are False.

Text Solution

Verified by Experts

The correct Answer is:
D
As ` q _ ("net") ` (enclosed charge ) = 0 , so ` phi = oint vecE. dvecS= 0 ` but ` vecE ` is not necessarily 0 as flux for same part can be positive while for other it can be negative.

Slection Of Gaussian Surface

Selection Of Gaussian Surface

Assertion(A):If Gaussian surface does not enclose any charge then vec(E) at any point on the Gaussian surface must be zero. Assertion(R ):No net charge is enclosed by Gaussians surface,so net flux passing through the surface is zero.

Find out flux through the given Gaussian surface.

Find out flux through given gaussian surface.

Assertion: No net charge can exist in the region where electric field is uniform. Reason: For any type of Gaussian surface selected within the region of a uniform electric field, the angle between electric field intensity and area normal is 90^@ everywhere. Hence, electric flux linked with the selected Gaussian surface is equal to zero. If the net electric flux is zero for some Gaussian surface then according to Gauss's law the net charge enclosed within the surface must be zero.
