Question

Question 1 3 pts Each of these cubic Gaussian surfaces contains charge as shown. Which has more total electric flux? 20 2d O A O They are the same O Not enough information to tell

PLEASE EXPLAIN WHY VERY THOROUGHLY

Answer 1

The total electric flux due to a given charge can be calculated using Gauss theorem. I am giving statement of Gauss theorem in the scanned sheet attached. According to it we can easily understand that total flux does not depend upon the size or shape of the Gaussian surface assumed .

Hence the answer for this question is OPTION B Because the flux will depend on the amount of charge. Since amount of charge is greater in B hence flux also greater in B.

Gauss Theorem: The net/total flux through a closed surface is proportional to the enclosed electric charge and is given by Flux phi = 1/elementof_0 times Q total flux = 1/E_0 times total charge enclosed/inside the closed surface. Electric flux does not affected when the size of Gaussian surface is changed In the Question in A charge is + Q and in B charge is + 2Q
