Physics 118A PROBLEM SET #7 Assigned: Wed.. 2/27/08 Young & Freedman Chapter 28 & 29 Due Thur. 3/6/08 no later than 5:00 PM Solve all problems algebraically, and insert numerical values as the last step. Show all your work, and explain your reasoning. BOX YOUR FINAL ANSWERS. While we encourage free discussion of the homework, each assignment is to be completed individually. Copying will not be tolerated. 1. Look at figure 28.46 on page 987. The current I is 5.00 A; the radius of the semicircle is 3.50 cm. Calculate the magnetic field B (magnitude and direction) at point P , the center of curvature of the semicircle a) due to the current in the semicircle. b) due to the current in the two straight sections. (Assume that the left straight section extends an infinite distance to the left, and the right straight section extends an infinite distance to the right.) 2. A long solid conducting wire of radius a carries current I , uniformly distributed over the cross section of the wire. The wire is surrounded by a concentric conducting tube of inner radius

    As a current student on this bumpy collegiate pathway, I stumbled upon Course Hero, where I can find study resources for nearly all my courses, get online help from tutors 24/7, and even share my old projects, papers, and lecture notes with other students.

    I cannot even describe how much Course Hero helped me this summer. It’s truly become something I can always rely on and help me. In the end, I was not only able to survive summer classes, but I was able to thrive thanks to Course Hero.

    The ability to access any university’s resources through Course Hero proved invaluable in my case. I was behind on Tulane coursework and actually used UCLA’s materials to help me move forward and get everything together on time.
