Homework set # 8 Problems: 19.2, 4, 11, 18, 19, 25, 30, 38 Solutions: 19.2 (a) For a positively charged particle, the direction of the force is that predicted by the right hand rule. These are: (a’) in plane of page and to left (b’) into the page (c’) out of the page (d’) in plane of page and toward the top (e’) into the page (f’) out of the page (b) For a negatively charged particle, the direction of the force is exactly opposite what the right hand rule predicts for positive charges. Thus, the answers for part (b) are reversed from those given in part (a) . 19.4 Hold the right hand with the fingers in the direction of v so that as you close your hand, the fingers move toward the direction of B . The thumb will point in the direction of the force (and hence the deflection) if the particle has a positive charge. The results are (a) toward top of page (b) out of the page , since the charge is negative. (c) zero force (d) into the page 19.11 From sin F BI L , the magnetic field is 3 0.12 N m 8.0 10 T sin 15 A sin90 F L B I

### What students are saying

• 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.
