Question

1. Which of the following electric charge transfers produces the same change in the total charge at points X and Y? I. +1 moved from point X to point Y II. -1 moved from point Y to point X III. +1 and -1 created simultaneously at point X a. I and I1 have the same effect. b. I and I1I have the same effect. c. II and III have the same effect. d. I, Il and III all have the same effect e. No two of these processes produce the same effect. One microcoulomb is: 2. less than the magnitude of the electron's charge. b. 6.3 x 101 times the magnitude of the electron's charge a. c. 1.6 x 1013 times the magnitude of the electron's charge. d. 6.02 x 10 times the magnitude of the electron's charge. e. none of these. Electrical charge interaction can be summarized by: a. 3. -charge repels other - charge. b. +charge repels other+ charge. -charge and+charge attract each other. c. d. All of these. e. Two neutral, conducting spheres are in contact with each other but insulated from the rest of the world. A negatively charged rod is brought near the right sphere. The spheres are separated and then the negative rod is removed. The result is that: a. the left sphere is-and the right sphere is + b. the left sphere is + and the right sphere is- c. the left sphere is neutral and the right sphere is - d. the left sphere is- and the right sphere is neutral. e. both spheres are neutral. Consider two point charges that are separated by a distance, 2r. If this distance between them is increased to 5 r, the force between the charges is: a. 1/25 as great as it had been b. 4/25 as great as it had been c. 1/9 as great as it had been d. 25 times as great as it had been e. none of these An electric field: a. surrounds a charge b. is said to exist in a region where a net force will act upon a stationary charge. c. is where corn and soybeans are grown beneath high voltage transmission lines. d. both a and b e none of these None of these. 4. 5. 6.
