Physics 219 Practice Exam 1 Summer 2004 Multiple Choice (100 points total) The following 18 multiple choice questions are to be answered on the OP-SCAN sheet with a pencil. There is no penalty for guessing and each correct answer is worth 5.56 points. 1. Three point charges are located on the x-axis. The first charge, q 1 = 10 μ C, is at x = -1.0 m. The second charge, q 2 = 20 μ C, is at the origin. The third charge, q 3 = - 30 μ C, is located at x = 2.0 m. What is the force on q 2 ? (a) 1.65 N in the negative x- direction (b) 3.15 N in the positive x- direction (c) 1.50 N in the negative x- direction (d) 4.80 N in the positive x- direction (e) 4.65 N in the negative x- direction 2. The electric field has a magnitude of 3.0 N/m at a distance of 60 cm from a point charge. What is the charge? (a) 1.4 nC (b) 120 pC (c) 36 mC (d) 12 μ C (e) 3.0 nC 3. An electron traveling horizontally from North to South enters a region where a uniform electric field is directed downward. What is the direction of the electric force exerted on the electron once it has entered the field? (a) downward (b) upward (c) to the east (d) to the west (e) to the north 1
