AT Cycle 15

🔴❗ 1: W*12/2, 🟡❗ 3: W*12/2a electric fields point charges (1)

Quiz on Rolling WITH Slipping

Today, after a daily quiz, we'll tackle some problems on electric fields due to point charges from Chapter 22:

Required: 7, 8, 14, 15, 16-17, 19, 1981B3, 2006aB3

Enrichment: Go on to problems in next post.

🟥 1: Th 12/3, 🟨 3: W*12/2 electric fields point charges (2)

Today, we'll continue to do some problems involving multiple point charges. (Note that these are from the AP Physics B test. The C test questions will be more difficult, but this is a review of what you should have learned last year.)

Required: 2000E2 (a-b), 1975B2, 2002bB5, 2003bB4, 2006bB3

You must do all of the parts of the problems which have to do with electric force and field, including the motion of a particle in the field. Parts that have to do with potential energy, work, or potential are optional for now, but if you finish early, then try to remember how to do these parts.

Homework: If you need to review last night's video, make sure you do so. Then watch this video on calculating the electric field due to a continuous distribution of charge.

❤️ 1: F 12/4a, 💛 3: F 12/4 continuous charge distribution (1)

Today, we'll start with a daily quiz. Then, 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: By next Tuesday, read this page on Electric Field Lines from The Physics Classroom. Make sure that you understand the rules for drawing electric field lines.

📕 1: F 12/4b, 📒 3: M 12/7 continuous charge distribution (2)

Today, we'll continue working on problems from last hour 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.
