PHYS 2020 Midterm: PHYS 2020 Exam
Document Summary
Below are some questions from old 2020 exams, largely from one i gave in phys 2020 a decade ago! This might give you an idea of the style of questions i ask - although the course (and exam emphasis) are a little different now, 10 years later! So, expect a little *more* long answer than this old one, on this year"s test Multiple choice: all answers must be bubbled in on your bubble sheet. (i suggest also circling the answers below, so you can easily check yourself when you get your exam back) There is always only one correct answer for each question: suppose you rub a wool cloth against a rubber rod (both initially neutral), and the rubber acquires a net negative charge of -2 mc. A negatively charged rubber rod is brought closer to the electroscope (but does not touch it)
