Document Summary
Name:______________________: please bubble in your version of the exam. You have version a: four point charges of varying magnitude and sign are arranged on the corners of the square of side d as shown in in the figure below. What is the value of the electrostatic potential at the empty corner a: 4. 50 104 v, 8. 99 104 v, 5. 62 104 v, -1. 87 104 v, 0 v. +2. 00 c: two equal point charges of 4. 0 c are situated along the x-axis at x1 = +2. 0 m and x2 = What is the current through the 9- resistor: 1 a, 0. 7 a, 0. 5 a, 0. 9 a, 2 a, a system of capacitors is connected across a 90-v dc voltage source as shown in the figure below. The current in the wire points to the right and is of magnitude i. E e: two straight wires are both carrying a current i = 7. 5 a.
