8/11 My return to campus will be delayed until August 13. 7/28 The solutions for test 3 are now available at the Noble Library Copy Center. 7/18 The solutions for test 2 are now available at the Noble Library Copy Center. 7/16 Please note that there is an error on the HW schedule for the day of July 18. All of the problems for July 18 are about Magnetism and thus should be from Chapter 29, not Chapter 28. 7/15 Problem P53 was inadvertently omitted from the online problems for July 10 - July 16. I have now added it to that webpage. It is also here. CHAPTER 26 53. A certain parallel-plate capacitor is filled with a dielectric for which Kappa = 5.5. The area of each plate is 0.034 m^2, and the plates are separated by 2.0 mm. The capacitor will fail (short out and burn up) if the electric field between the plates exceeds 200 kN/C. What is the maximum energy that can be stored in the capacitor? 7/10 The solutions for test 1 are now available at the Noble Library Copy Center. 7/05 Problem P88 was inadvertently omitted from the online problems for July 1 - July 8. I have now added it to that webpage. It is also here. CHAPTER 25 88. Three particles with the same charge q and same mass m are initially fixed in place to form an equilateral triangle with edge lengths d. (a) If the particles are released simultaneously, what are their speeds when they have traveled a large distance (effectively an infinite distance) from each other? (Measure the speeds in the original rest frame of the particles.) Suppose, instead, the particles are released one at a time: The first one is released, and then, when the first one is at a large distance, a second one is released, and then, when that second one is at a large distance, the last one is released. What then are the final speeds of (b) the first particle, (c) the second particle, and (d) the last particle? 7/02 The Old Tests, both with and without solutions, are now available in the Noble Library Copy Center.
