Lecture 10: iq08

1. Electric field due to a uniformly charged disk (cont’d)

2. Field pattern of a parallel plate capacitor

3. Various cases of the r-dependence of the field: 1/r³, 1/r², 1/r, 1/r⁰=const.

4. The sphere-rod problem. Q15.7b and digressions.

5. Electric flux, outgoing flux from a box.

6. Outgoing flux from a point charge

o S₁: a sphere

o S₂: arbitrary shape

o Gauss law: Valid for any S and any charge distribution enclosed by S.

Announcements:

1. Read the remainder of chapter 22 on Gauss law. Begin on HW16-3.

2. Review on midterm1: Go through the lesson plan (highlights of the textbook) and the physics of all homework problems.
