Physics 1120, General Physics 2: Electricity, Magnetism, and Optics
Instructors: Steven Pollock and Victor Gurarie
Does everything really have a charge equal to an integer times the electron's charge? With this apparatus a lab in California spent five months measuring the charge of 40 million oil drops hoping to find an exception. Here's what they found.
Week 2 Highlights: Electric Fields
Happy Labor Day, enjoy!
There are always 3 different things you need to turn in each week. See "assignments" link on the left.
1) CAPA homework (online, due Friday night - technically, by 8 AM Sat morning)
2) Tutorial homework (submitted hard copy, at the START of your recitation on Tuesday) and
pretests (online, due Mon night - technically, by 8 AM Tuesday morning)
All are on a regular schedule, every week!
Don't forget about # 3, you need to do the first pretest over the weekend (or on Monday)!
Chapter 26 on E fields,
Note: Since we want you to do p. 76 of the Tutorial HW book as part of next
week's assignment, it's awkward to have you turn in p. 75 this week
(because p. 76 is on the back!) So,
you have a choice: photocopy the page (so you can work on p. 76 next week), or
do both p. 75 and 76 now
and hand them both in Tuesday, or just *keep* p. 75
and turn it all in next week. It's all fine with us, decide what's easiest for you...
- If you haven't done it yet, you can still do the CLASS survey for 1120 (it won't be up much longer!) (This is worth participation credit). If you choose not to participate, that's ok - go to the link, and merely fill in your name and ID before submitting. But we really appreciate your taking the time to take the survey - it's helpful for us to improve this course!)
- Please register your clicker soon - just go to our clicker info page.
- The "virtual office hours" link on the left has responses to
questions people have been asking me. Check it out if you have any
questions - perhaps I've already answered it!
- We also have an 1120 CULearn page . We'll post your grades there later this term. There is also a "threaded messages" list - you are welcome to ask each other questions about the course, even the homework there, and respond to one another. I will be monitoring this occasionally, so please use good judgement and common sense. If anyone uses this to copy answers, tell formulas, or otherwise sabotage the learning goals of the course, we'll just turn it off. But I think it's great for you to ask questions, discuss the problems, give hints, talk about where you went to get help or how you figured something out, and so on. Use it as a resource to collaborate (but not to cheat!) When in doubt about how far you can go in "giving help" to other students' questions: if you feel comfortable knowing that I'll be reading it, then it's probably fine!

decent web connection to watch them) These links will remain available
from the "Many useful or interesting links" near the bottom on the left...
Here's the old home page from week 1.
