NAME PHYS-1200 PHYSICS II QUIZ 1 SEPTEMBER 29, 2004 SOLUTIONS PART A. 1. C 5. E 2. D 6. E 3. C 7. B 4. B 8. A PART B . 1. a) The field at A is smaller than at B. The magnitude of the electric field within a uniformly charged insulating sphere is linearly proportional to the distance from the center of the sphere. Since B is farther from the center than A , the field is larger at B . b) The field at A is greater than at C. The field at C is zero, since a Gaussian sphere that exactly fit the hole in the charge distribution would contain no charge. c) The field at B is greater than at D. Both B and D are the same distance from the center of the charge distributions. However, a Gaussian sphere that just enclosed the charge in figure 1 would enclose more charge than a similar Gaussian sphere in figure 2. d) The field at A is equal to that at E. Gaussian spheres of radius R /2 centered on the charge distributions in figures 1 and 3 would contain the same amount of charge. 2.
