The sketch below shows equipotential surfaces between two charged conductors (shown in solid black). Various points on the equipotential surfaces near the conductors are labeled A, B, C, ... through I. Use those points as the answer choices for questions 5 and 6. 0.4 m H. - 70 V - 60 V A - 50 V -40 V - 30 V - 20 V 5. At which of the points A through I does the electric field have the greatest magnitude? Recall that E-field can be measured in units of Volts / meter. + 20 V + 40 V H 6. At which of the points A through i will an electron have the greatest potential energy? V B7. What is the direction of the electric field at B ? (B) Toward C E. down into the page A. Toward A C. up out of the page D. Toward D 8. Positive charge +Q is uniformly distributed on the lower half of a semicircular rod and negative charge-Q is uniformly distributed on the upper half, as shown. What is the direction of the electric field at point P, the center of the semicircle? A. 1 B. C. / В. D E. . Two particles of the same mass have charges +3Q and -2Q, respectively. They are shot into a region that contains a uniform electric field as shown, in the negative y direction. The particles have the same initial velocities in the x polnt of entry direction. The lines, numbered 1 through 5, indicate possible paths for the particles. What will be the resulting paths for these particles? A. path 1 for +3Q and path 4 for -2Q C. path 4 for +3Q and path 3 for -2Q E. path 5 for +3Q and path 2 for -2Q B. path 3 for +3Q and path 2 for -2Q D. path 2 for +3Q and path 5 for -2Q 5. none of the above choices are correct
