This coming week (week 5 of Winter quarter already?!) we will be checking your problem set and lab notebooks in all subjects.
As a reminder, spot checks of problem set and lab notebooks can occur at any time. The main reason for this announcement is so that we can expect you to have problem set notebooks with you Monday.
The entries you record in any of these notebooks are simply a record of the work you have done in the corresponding part of the program; “fixing” or “completing” notebooks is not extra work that you should do in response to an announced notebook check, but part of your ongoing learning process. In this spirit, you should not be making a special effort to polish your problem set notebooks for Monday; rather, you should be completing problem sets as usual, studying for your math exams, and turning in the notebooks simply as a record of the work you have already been doing in support of your learning, rather than as pieces of “busy work.”
Here is Quiz 10 for corrections. Since you are already doing #3 as for your IDEAl solution, I’ll evaluate that submission in lieu of re-writing it on any corrections you turn in.
Speaking of #3, Example 20.6 outlines how to solve the problem. The Evaluate step in the text is very compressed, and I want you to give a more detailed explanation of what is going on, in your own words and maybe pictures, than Wolfson offers. What I’m most interested in is your understanding. Also note that some elements of this problem are the same as in this week’s Math Lab (particularly the way one handles the element of charge dq). The main difference is that in Math Lab you found solutions for arbitrary locations in the plane of the ring, while this problem asks for E at a specific location on the axis of the ring, but in a different plane 15 cm away. You might think about what change you’d need to make to your Mathematica notebook to solve the fully 3-dimensional problem – you may be surprised at how small the change would be!
