The FINAL EXAM itself is uploaded here as a Word document attachment. The approved FL Rules of Civil Procedure are also uploaded both here and on Canvas (see announcements page). These are the ONLY materials you are permitted to have present with you. Otherwise, this is a closed-book/materials midterm quiz.  JULY 28 2025 FINAL EXAM.docx FL RULE CIV PRO 2025 APPROVED QUIZ COPY-1.pdf For uploading your answers: you can download the Word version of the exam and clearly write your answers within that Word document and upload it here.  If any questions, please do let me know. Thanks! 

Resistors in combination: A 4.00

RC circuits: For the circuit shown in the figure, the switch S is initially open and the capacitor voltage is 80 V. The switch is then closed at time t = 0. What is the charge on the capacitor when the current in the circuit is 33

Motion of a charged particle: In the figure, a proton is projected horizontally midway between two parallel plates that are separated by 0.50 cm.  The electrical field due to the plates has magnitude 610,000 N/C between the plates away from the edges. If the plates are 5.60 cm long, find the minimum speed of the proton if it just misses the lower plate as it emerges from the field. (e = 1.60 × 10-19 C, 

Coulomb’s law: In the figure Q =  5.8 nC and all other quantities are accurate to 2 significant figures. What is the magnitude of the force on the charge Q? (k = 

Dielectrics: A 6.0

Coulomb’s law: In the figure, charge q1 =  3.1 × 10-6  C is placed at the origin and charge  q2 =  -8.7 × 10-6 C  is placed on the x-axis, at x = -0.20 m. Where along the x-axis can a third charge Q = -8.3 µC be placed such that the resultant force on this third charge is zero? 

Resistors in combination: Four resistors are connected across an 8 V DC battery as shown in the figure. The current through the 9-

Coulomb’s law: In the figure, all the charges are point charges and the charge in the middle is Q = -3.1 nC For what charge will charge  be in static equilibrium?

Energy in capacitors: An ideal parallel-plate capacitor consists of a set of two parallel plates of area A separated by a very small distance d. When this capacitor is connected to a battery that maintains a constant potential difference between the plates, the energy stored in the capacitor is U0. If the separation between the plates is doubled, how much energy is stored in the capacitor?
