Conceptual Questions: These questions are to be answered With a short para graph. Problem 1. Choose one answer. The electric eld at a point and the force on a negative charge placed at that point: (a) Have equal magnitudes. (b) Are not related. (c) Have the same direction. (d) Have opposite directions. (e) Are both zero. Problem 2. You have some equipotential lines with the value of the potential for them (Fig. 1). (a) Rank the magnitude of the electric field at the designated points. (b) Draw the electric field at the designated points. B C D 20 0 -20 Figure 1: Rank and draw the electric field at the designated points.Complete Solution Questions: These problems are to be answered with detailed calculations . Problem 3. (a) Find the electric potential and the electric field at point A (Fig. 2). (b) Is there a point where the electric potential will be zero? If yes, where is it? (c) Is there a point where the electric field will be zero? If yes, where is it? 91 = 15 uC 0.12 m - - - A - - - - - - - -X 0.12 m 0.36 m - - 92 = 15 uC Figure 2: Charge configuration.Problem 4.
