Daily Check-in: E-field continuous distribution
Today, we'll do some problems which require us to calculate the electric field due to a continuous distribution of charge:
Required: Electric field integrals #2 only (WHERE you put theta matters in what the integral looks like, but the result should be the same if you've chosen the correct limits. Here's one solution, and here's another, and here's yet another), 1981E2, redo Giancoli Example 21-10 (p. 559), and state why the book chose to solve with d(theta) rather than dy. Also, Halliday Chapter 22 #28, 29, 32, 31
Enrichment: Halliday Chapter 22 #24, 33, 65
Homework: Study for Rotation Assessment Monday, December 12th. Continuous distribution of charge problems are due in ✏️ Google Classroom on Thursday, December 15th at 10pm (but I recommend you finish by Wednesday night).

Homework: Continuous distribution of charge problems are due in ✏️ Google Classroom on Thursday, December 15th at 10pm (but I recommend you finish by Wednesday night).
By Wednesday's class, read this page on Electric Field Lines from The Physics Classroom. Make sure that you understand the rules for drawing electric field lines. Next time, we'll be starting to talk about electric flux. If you don't remember anything about the concept of flux (we studied magnetic flux last year), watch the first 3:43 in my Faraday's Law video:

With the last half hour of class, we will start the next lab activity. We'll review what you should have learned about flux last year: last year, we talked about magnetic flux in the context of induction, and this year, we'll find out more about electric flux.
Homework: By next class (Wednesday), read this page on Electric Field Lines from The Physics Classroom. Make sure that you understand the rules for drawing electric field lines. If you don't remember anything about the concept of flux, watch the first 3:43 in my Faraday's Law video.

📕 2: W 12/14, 📒 4: W 12/14b - flux
Today, we'll review electric field line by playing with an online applet (Falstad 2-D Electrostatic Fields) while starting on this worksheet: Flux Using Applet. We'll explore the concept of flux. We'll talk about what flux is in general, and we'll figure out how to represent electric flux. Then, we'll go back to the online applet which will help us to understand even more about flux. Watch this video for directions on using the applet.
Homework: QUIZ on Electric Field Integral (no Gauss's Law) Friday, December 16th. Continuous distribution of charge problems are due in ✏️ Google Classroom on Thursday, December 15th at 10pm. TONIGHT (Wednesday), finish the worksheet which was given out in class. Then, watch the following two videos on Gauss's Law:
