Spherical service Gaussian questions.

Question 15 1 pts The figure shows a cubical Gaussian Surface; at the center of the cube is a point charge (the circle) with charge 189. What could explain the flux through BOTTOM face of the Gaussian Surface being 2q,/Eg? TOP BOTTOM An unshown positive charge located above the TOP face of the Gaussian Surface. An unshown negative charge located below the BOTTOM face of the Gaussian Surface. None of the other answers can explain this situation. An unshown positive charge located below the BOTTOM face of the Gaussian Surface. O An unshown positive charge located within the Gaussian Surface.13. The figure below shows a spherical Gaussian surface of radius R. A very long thin rod passing through the center of the sphere has a uniform linear negative charge density -2. A charge -q is located inside the Gaussian surface. Located outside is another charge +q. What is the ner electric flux through the Gaussian surface? R spherical Gaussian surface A. La B. C. D. E.Select all the statements that are TRUE about Gauss' Law. O A Gaussian surface is a virtual surface used only for calculations. O The charge qenc must be all the charge in the problem. O The area vectors on the Gaussian surface must all be in the same direction as the electric field on the surface. O Gauss's law holds only for symmetric charge distributions. O A Gaussian surface must be a closed surface (must cover a volume). O The charge genc must be all the charge lying within the Gaussian surface. O The electric field E in the integral is due only to the charge qenc O The charge qenc must be all the charge lying on the Gaussian surface. O A Gaussian surface must be a conductor. O If the net flux through a Gaussian surface is zero it is certain there are no charges enclosed within the Gaussian surface. O Gauss' Law calculates the electric field only at the location of the Gaussian surface
