PHY2054 - Spring 1999

Chapters 18 & 19 Suggested Problems

While homework will not be graded, it is essential practice for learning the material. Thus I have provided the accompanying list of homework problems selected from the textbook, grouped by topic. My recommendation is to work some of the appropriate homework problems following each lecture to ensure that you fully understand the concepts and how to apply them. They also form a useful basis for asking questions during section.
 

Coding for list:

Q = Question in textbook; P = Problem in textbook ; S = Section in textbook

*** The interactive field line demo does not work properly on some browsers.  The right figure should display field lines when you click the buttons on the left panel - if not, here's an alternative way to view the field lines.  Pick the Q1 and Q2 values you want from the table below.  Then click on the word "Link" to the right and *presto* you'll get the correct figure. Enjoy.
