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.The figure below shows a rendering in two dimensions of a charged particle at the origin of an xyz coordinate system. Surrounding the particle is a spherical, mathematical surface, called a Gaussian surface. It is not a physical surface that you can touch. The intersection of the Gaussian surface with the xy plane is a circle, as the figure shows. Spherical Gaussian surface Particle of charge q Intersection of Gaussian surface with xy plane
