6/4/2020 Quiz: Quiz 1 Quiz 1 Started: Jun 4 at 10am Quiz Instructions This quiz tests on the first three experiments in Lab 2: Electrostatics, Electric Potential and Field Mapping and Capacitance. It provides the student with a chance to become acquainted with taking a Canvas quiz, and be better prepared for the final exam in PHY 2092. Question 1 5 pts Triboelectrification is the term for The process by which electrical sparks are created when one pulls an electrical cord out from a wall outlet. The process by which a nearby, electrically isolated, charged object causes electrons to change their position on an uncharged object. The process by which Native American Tribes learned to make sparks fly from large fires. The process where two objects become oppositely charged when they are rubbed together and then separated. The process by an object at a high electric potential is placed in physical contact with an object at a lower electric potential. The process by which electrical sparks are generated when a candle is put in a microwave oven and the oven is turned ON. Question 2 5 pts Two conducting spheres are mounted on electrically insulating supports. The right side of sphere A is charged https://fit.instructure.com/courses/563178/quizzes/881593/take 1/6 6/4/2020 Quiz: Quiz 1 neutral. positively. negatively. Question 3 5 pts Select two correct answers. The electric potential at a point some distance from a long, charged, straight wire is proportional to the inverse of the distance from the wire to the point. the square of the inverse of the distance from the wire to the point. the magnitude of the product of the charge on the wire and the charge at the point. the square of the distance from the wire to the point. the magnitude of the charge on the wire. the magnitude of the charge at the point. the logarithm of the distance from the wire to the point. https://fit.instructure.com/courses/563178/quizzes/881593/take 2/6 6/4/2020 Quiz: Quiz 1 Two, large, parallel, metal plates are connected to a DC power supply. The plates are squares. The plate connected to ground is at x = 0 and sits in the y-z plane. The x-axis runs perpendicular to the plates. The other plate is connected to the positive terminal of the power supply. Question 4 5 pts For the parallel plates mentioned above, the DC power supply is set to 45 Volts and the plate on the right is at x = 15 cm. What is the magnitude of the electric field at a point on the x-axis where x = 6.0 cm? Answer with a number in the format ### in Newtons per Coulombs. Question 5 5 pts For the parallel plates mentioned in the previous question, what is the shape of an electric potential surface for all points in the x-y plane that sit between the plates? https://fit.instructure.com/courses/563178/quizzes/881593/take 3/6 6/4/2020 Quiz: Quiz 1 a curved plane that increases in height as x increases a flat plane that slopes up as x increases a flat plane parallel to the x-y plane a curved, symmetric cone with its peak at the center of the plates a curved plane that decrases in height as x increases Question 6 5 pts Suppose you are to design a circuit made of only capacitors. The design requirement is the total capacitance must be 7.5 micro-Farads. However, you only have a box of identical capacitors each with a capacitance of 10 micro-Farads. Write a short sentence describing how many capacitors you will use and how you will connect them to each other to meet the design requirement.

Both have air as the material between the plates. The plates of capacitor 1 are square with an edge length of b centimeters. The plates of capacitor 2 are also square with an edge length of 1.8b. The plates of C1 are separated by 0.2 cm. The plates of C2 are separated by 0.3 cm. Calculate the ratio C2 / C1. Round your answer to a number in the format #.## Question 8 5 pts Two capacitors, both of capacitance 47 micro-Farads, have a manufacturer's uncertainty in their value of ± 5%. If you connect both capacitors in parallel, what is the propagated absolute error in the equivalent capacitance? Round your answer to a number in the format #.# in micro-Farads.
