(new) To give quick 2-4 questions quizzes use /All/ and /All1/ (need two pages to avoid the 2048 kB maximum.)
Equations sheets are under construction and are based on
- Physics equations/Equations
- Quizbank/Electricity_and_Magnetism_(calculus_based)/Equations
The students can use the next section to see what "might" be on the test, and the equations shown can be displayed for the students to use:

University Physics Semester 2

This unit has 11 exams (tests) that can viewed by clicking the links (e.g., /T1/). They are classroom-ready exams based on the collection of quizzes shown below each exam. The fraction indicates the ratio of the number of questions randomly selected to the number of questions on each quiz. Students can access these quizzes using either the (uneditable) permalink or directly via links to subpages of QB. Students and instructors can also view all the questions on this unit's /Questions list. Ideas for use by instructors can be found at Quizbank/Instructions. <section begin=1/>

Errata

QB/d_cp2.5

Question 2: The angle is above the x-axis not the −x axis.
Question 4: There is an error of 10⁹ which can be removed by changing nC to C (nano-Coulombs to Coulombs) in the question.
Question 5: I forgot to give you a value for z. Take z=1 until this gets fixed.
Question 6: Perhaps the student should be informed that the approximation of the field near an infinite plane should be used here.^[1]

Equations for this test

QB/d_cp2.6: Question 1: Replace C by nC for both charges in the question.S
