Multiple-choice questions may continue on the next column or page – find all choices before answering. 001 (part 1 of 3) 10.0 points An electron traveling at 4 × 10 6 m / s enters a . 06 m region with a uniform electric field of 283 N / C , as in the figure. The mass of an electron is 9 . 10939 × 10- 31 kg and the charge on an electron is 1 . 60218 × 10- 19 C . − − − − − − − − − . 06 m + + + + + + + + + ˆ ı ˆ 4 × 10 6 m / s Find the magnitude of the acceleration of the electron while in the electric field. Answer in units of m / s 2 . 002 (part 2 of 3) 10.0 points Find the time it takes the electron to travel through the region of the electric field, assum- ing it doesn’t hit the side walls. Answer in units of s. 003 (part 3 of 3) 10.0 points What is the magnitude of the vertical dis- placement Δ y of the electron while it is in the electric field? Answer in units of m. 004 10.0 points The diagrams below depict three electric field patterns. Some of these patterns are physi- cally impossible. Assume these electric field patterns are due to static electric charges outside the regions shown. (a) (b) (c) Which electrostatic field patterns are phys- ically possible? 1. (a) only 2. (a) and (b) 3. (c) only 4. (b) and (c) 5. (b) only 6. (a) and (c) 005 (part 1 of 2) 10.0 points Given : V sphere = 4 π R 3 3 , and A sphere = 4 π R 2 ....
