Unformatted text preview: it to generate this magnetic moment? a) b) c) d) e) 1 femtometer/second 24 micrometer/second 24,000 km/s 75,000 km/s 240,000 km/s 9: The picture shows a region bounded by two charged infinite plates. The left one is positively charged, the right is negatively charged. Between the plates, we place an electric quadrupole. Contours on the figure are equipotential lines separated by 10 V. What is the magnitude and direction of the electric field at point A? a) b) c) d) e) f) + - 10 N/C 100 N/C 1000 N/C 100 N/C 10 N/C 1000 N/C A 1 cm 10: (5 points) Consider the circuit below. The switch remains closed for a long time, then is suddenly opened. What is the current in the resistor on the right hand side just after the switch is opened? a) b) c) d) e) 2VB/3R VB/3R 3VB/2R VB/6R 3VB/R R VB C R R R 11: (5 points) The point labeled A on the object is 15 cm from a converging lens with a 5 cm focal length. Point A is 3 cm above the horizontal line. Consider the two rays shown below: the first leaves A and strikes near the top of the lens, the second leaves A and strikes near the bottom of the lens. Where do these two rays cross? Please provide both the x and y positions of the crossing point, measured from an origin at the center of the lens. a) b) c) d) e) x = 7.5 cm, y = -1.5 cm x = 10 cm, y = 3 cm x = 6.6 cm, y = -1.5 cm x = 10 cm, y = -3 cm x = 7.5 cm, y = 2 cm A B C 12: (5 points) A diffraction grating has 1500 vertical slits per centimeter. Light striking this grating is an equal mix of 400 nanometer blue and 600 nanometer red light. Draw what you would see on a 20 cm wide screen 1 m away from the grating. The center of the screen is placed where the undeflected beam would pass. Label each feature as made up of blue light, red light, or both, and include all locations where light strikes the screen. 10 cm 5 cm Original beam 5 cm 10 cm 13: (5 points) X-ray diffraction can be used to determine the arrangements of atoms in molecules or solids. Imagine a new molecule made in of interconnected ro...
