This is a closed book exam. I understand that I am not allowed to use any notes or information other than that specifically authorized for use in this exam by the instructor. I may use a pocket calculator but ONLY for the purpose of numerical computation. I must show complete work to receive full credit.
Partial credit is given only for work shown.
Neatness and clarity will ensure a proper grading. There are 7 questions and 8 pages. I have checked my copy and find it has no missing pages. Sign your name here. Three charges are fixed at the corners of a square as shown.
