each; 8 pts. total) (4 pts. 2. Given the following configurations of equipotential lines, sketch the electric fields in these regions. (a) a negatively charged flat sheet (in 3-dimensions, it is a bar) and a positively charged point charge, as (b) two positive point charges. Here, consider the the negative charge to be spread out evenly at infinity shown in the figure on the left. (very far from the charge, , as shown in the figure on the right). Figure 9 3. In your own words, write the rules for sketching electric field lines from equipotential configurations. Give your answer in 2-3 well written sentences (2 pts.)
