University Physics Semester 2[edit]

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.

Errata[edit]

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