ultiple Choice-20 Points 1. Which of the charges shown on the diagram are positive charges? 3. .Only A B. A & B 4. Only B C. D. B&C E. Only C At which of the following points is the magnitude of the electric field greatest? 2. 6. A. 1 B. 2 C. 3 D. 4 Points 1 and 2 are the same distance from Point 3 is that sarme distance from the charge C.) Refer to this diagram for the first 3 questions E. All have the same magnitude 9. 3. Ifa proton is released from rest at point 1, which of the following would be the initial direction of its motion? 10. B. C. E. 4. In the diagram below, a point charge creates an electric field at point P that points to the right. If a solid aluminum cube is inserted between the point charge and point P as shown, which will the resulting char the electric field at point P? A. Gets weaker& points to the left B. Gets weaker& points to the right Q, C. Gets stronger& points to the left D. Gets stronger&points to the right E. No electric field 5. In the diagram below, two fixed point charges exist in space. In which of the regions could we find that when we place a test charge at that point, it experiences no acceleration? A. Region I B. Region 2 C. Region 3 Region 3 Region 1... Reg D. All of the above E. None of the above

Explanation / Answer

1.as the electric field is outward from A and B, so
