On your answer sheet, draw and color the Dif you agree with the statement. Draw and color the @ if you disagree with the statement. EMOTICON STATEMENT 1. Electric flux (DE) is a measure of the number of field lines passing parallel through a surface. 2. Electric flux is a vector quantity, which means it has magnitude and direction. 3. The flux through a solid surface is positive if the field is directed out of the region contained by the surface. 4. The charge distribution may be expressed in terms of linear charge density, surface charge density, or volume charge density. 5. You don't need to identify a Gaussian body; you need a Gaussian surface. B. Draw and color the @ if the second clause agrees with the first clause. Draw and color () if it does not. First Clause Conjunction Second Clause Emoticon 1. The electric flux is DE = 0 | because the electric field (E) is parallel (edge-on) to the surface. 2. It is a Gaussian surface because the flux or electric field is of a cylinder produced on a point charge. 3. The magnitude of the | because the charges of a conductor electric field inside a reside at its surface. conducting sphere is equal to zero 4. The total flux through the | because the negative flux directed entire closed surface is into the region is canceled zero out by the positive flux directed out of the region. 5. If the electric field makes because the magnitude of the flux an angle with the direction should be proportional to the normal to the flat surface, it component of the field will be solved using the perpendicular to the surface. formula DE = EA cos 0Ito Ang GAUSS-to Kong Problemahin Il.
