2. A circular surface is shown in perspective view at right. a. The surface is held to the left of a positive point charge +Q as shown. i. At each labeled point on the surface, draw and label an area vector dA, dAz, etc. ii. At each labeled point on the surface, draw and label the electric field E, E2, etc. iii. Is the net electric flux through the loop due to the charge positive, negative, or zero? Explain your reasoning. Perspective view Circular loop of area A 63 b. Use your answers above to write an expression for Denet through the entire surface. +Q
