Question

If the net electric flux through a closed surface is zero, then we can infer
(A) no net charge is enclosed by the surface.
(B) uniform electric field exists within the surface.
(C) electric potential varies from point to point inside the surface.
(D) charge is present inside the surface.​

Answer 1

Answer:

(A)

Explanation:

Flux is surface integral of Elec Field across a closed surface..

If charge enclosed is 0 .. then Flux is 0

Answer 2

If the net electric flux is zero, then no net charge is enclosed by the closed surface.

Explanation:

• Net electric flux is highly dependent on the net electric charge enclosed by the surface.
• In a closed surface, if the net electric flux is zero, then the net electric charge will be also zero.
• Since electric flux is defined as the rate of flow of electric field in a closed area and if the electric flux is zero, the overall electric charge within the closed boundary will be also zero.
