(5 pts) Three charges of equal magnitude are fixed at the corners of an equilateral triangle. The sign of each charge is indicated in the figure below. Circle the direction closest to the direction of the electric field if measured at the black point. + FV III Explain: (Drawing electric field vectors may help you receive partial credit) Explain:(iv) (5 pts) Rank the electric flux through the closed surfaces whose cross-sections are shown below from least to greatest. a -2.0 X 10 8 C -3.0 X 10 6 C End cap 4.0 X 10 6 c of area + 40 X 10 4 ma + + + + + Conductor + + + a -2.0 X 10 6 C 3.0 X 10 B C (T = 20 X 10 0 C/m 5.0 X 10 6 C (a) (b) (c) (d) Least Greatest Explain
