Question

Gaussian surfaces A and B enclose the same positive point charge. The area of surface A is two times larger than that of surface B. How does the total electric flux through the two surfaces compare? a. The total electric flux through surface B is four times larger than that through surface A. b. The total electric flux through surface B is eight times larger than that through surface A. c. The total electric flux through surface A is four times larger than that through surface B. d. The total electric flux through the two surfaces is equal. c. The total electric flux through surface A is eight times larger than that through surface B.

Explanation / Answer

Correct option is – d

Explanation - Electric flux through a surface, E = Q/0

Since charges enclosed by the two surfaces are the same hence electric flux through them are also the same.
