22 Reading Chapter Questions & Concept Questions Reading Questions If a positively charged particle is released in an electric field pointed west, the particle will begin to move towards a) the east. b) the west. c) the north. d) the south. e) It does not move. Electric field lines represent a) only the direction of the electric field. b) only the magnitude of the electric field lines. c) the force and the magnitude of the electric field. d) the path a positive point charge will follow in an electric field. Which statement is false? a) The electric field obeys the principle of superposition. b) The tangent to an electric field line at a point gives the direction of the field at that point. c) The density of the electric field lines is directly proportional to the strength of the field. d) Negative charges are sources of electric field lines and positive charge sinks. Concept Question: In the figure are shown two square arrays of charged particles. The squares, which are centered on point P, are misaligned. The particles are separated by either d or d/2 along the perimeters of the squares. What is the magnitude and direction of the net electric field at P? A. 6kq to the left 2 d B. 6kq to the right 2 d C. 0 D. kq to the left 2 E. F. d kq to the right 2 d Another answer Concept Question: In the figure are shown two square arrays of charged particles. The squares, which are centered on point P, are misaligned. The particles are separated by either d or d/2 along the perimeters of the squares. What is the magnitude and direction of the net electric field at P? Simplify! D. kq to the left 2 d Concept Question: Consider the four field patterns shown. Assuming there are no charges in the regions shown, which of the patterns represent(s) a possible electrostatic field: 1. A 2. B 3. C 4. D 5. E 6. F (a) (b) (b) and (d) (a) and (c) (b) and (c) some other combination Concept Question: Consider the four field patterns shown. Assuming there are no charges in the regions shown, which of the patterns represent(s) a possible electrostatic field: B (b) Since there are no charges in the patterns, electric field lines should not stop or start in the field of view. Also, electric field lines do not form loops. They start at positively charged particles and end at negatively charged particles. Reading Questions Linear charge density is (a) the total charge on a one-dimensional object. (b) the product of the charge on the object and the electric field component perpendicular to the (c) object. the amount of charge per unit length. (d) not discussed in the reading. An electric dipole is composed of two charged particles of magnitude q, separated by a distance d. The charged particles have (a) the same sign, positive. (b) the same sign, negative. (c) opposite sign. (d) (a) or (b). Which statement is true? (a) The electric flux through a surface is inversely proportional to the net number of electric field lines passing through a surface (more field lines ... less flux). (b) Flux is always positive. (c) Area is a scalar quantity, but flux is a vector quantity. (d) To store flux, one uses a flux capacitor. (e) (a), (b), and (c) (f) None of the above. Concept Question: The figure shows three nonconducting rods, one circular and two straight. Each has a charge of magnitude Q along its top half and another along its bottom half. For which rod is ^ the direction of the net electric field at point P in the positive y direction? A. (a) D. (a) and (c) B. (b) C. (c) E. None of the above. Concept Question: The figure shows three nonconducting rods, one circular and two straight. Each has a charge of magnitude Q along its top half and another along its bottom half. For which rod is ^ the direction of the net electric field at point P in the positive y direction? A. (a) (Use the principle of superposition!) Concept Question: A negatively charged sphere is located on the rotation axis of a positively charged ring (dashed line). Both the ball and the ring are made of plastic (an insulator). The ball is released from a position above the ring (positive z) and left for a long time. Ignore frictional forces. Upon your return, the ball will be A) stopped at the same initial spot. B) somewhere on the positive z-axis far away from the ring. C) somewhere on the negative z-axis far away from the ring. D) stopped at the center of the ring. E) oscillating back and forth through the ring. Concept Question: A negatively charged sphere is located on the rotation axis of a positively charged ring (dashed line). Both the ball and the ring are made of plastic (an insulator). The ball is released from a position above the ring (positive z) and left for a long time. Ignore frictional forces. Upon your return, the ball will be E) oscillating back and forth through the ring. When the sphere is above the ring it is being pulled down. When it is below the ring it is being pulled up. Since there is no loss of energy to the surroundings, the ball will just oscillate back and forth.
