2026 RIO SALADO physics 112 midterm QUESTIONS AND
CORRECT ANSWERS (GRADED A+) | VERIFIED
ANSWERS
DESCRIPTION
This Rio Salado PHY-112 (General Physics II) Midterm Study Guide is a high-yield
preparation tool specifically engineered for students mastering Electricity and
Magnetism. This bundle is meticulously aligned with the Rio Salado curriculum,
focusing on the algebra-based problem-solving and conceptual understanding required
for the 2025–2026 testing cycles.
What’s Included:
• 50+ High-Yield MCQs: Practice questions modeled after actual midterm
assessments, focusing on Coulomb’s Law, DC Circuits, and Magnetic Fields.
• Verified Answers & Rationales: Every question includes a bolded correct
answer and a detailed rationale in italics to ensure you master the "Physics why"
behind every formula application.
• Essential Formula Sheet: A rapid-reference guide for the "Big 5"
topics: Electrostatics (
), Capacitance (
), Ohm’s Law (
), Kirchhoff’s Rules, and Magnetism (
• Right-Hand Rule (RHR) Guide: Clear, step-by-step instructions for determining
the direction of magnetic forces and fields—a frequent point of confusion on the
exam.

, • Circuit Analysis Workbook: Practice identifying Series vs.
Parallel configurations for both resistors and capacitors, including how to
calculate equivalent resistance and capacitance.
Key Topics Covered:
1. Electrostatics: Mastering the inverse-square law, electric field lines, and the
relationship between potential and work.
2. Capacitors: Understanding dielectric constants, energy storage (
and RC time constants.
3. Current & Resistance: Differentiating between Ohmic and Non-
Ohmic materials and calculating power dissipation (
4. Kirchhoff’s Rules: Applying the Junction Rule (Charge) and Loop Rule
(Energy) to solve complex circuits.
5. Magnetism: Calculating forces on moving charges and wires, understanding
solenoids, and applying Faraday’s and Lenz’s Laws.
Why Use This Guide:
PHY-112 is a fast-paced course where conceptual errors can lead to wrong
calculations. This guide uses active recall to help you differentiate between similar-
looking formulas and ensures you can confidently apply the Right-Hand Rule to any
magnetic scenario.
RIO SALADO PHY-112: GENERAL PHYSICS II – MIDTERM EXAM
PRACTICE BATCH | 50 QUESTIONS & VERIFIED ANSWERS (GRADED A+)
1. According to Coulomb’s Law, if the magnitude of one of the two charges is
doubled, the force between them:
A) Is cut in half.
B) Doubles.

, C) Quadruples.
D) Remains the same.
Rationale: The force is directly proportional to the product of the charges (
). Doubling one charge doubles the force.
2. The unit of Electric Field (E) is expressed as:
A) Volts per Coulomb.
B) Newtons per Coulomb (N/C).
C) Joules per Newton.
D) Amperes per Volt.
Rationale: By definition,
, which translates to force per unit charge.
3. When two resistors (
and
) are connected in series, the total resistance is:
A)
B)
C)
D)
Rationale: In a series circuit, there is only one path, so resistances add linearly.
4. A dielectric material is used in a capacitor to:
A) Decrease the capacitance.
B) Increase the capacitance by reducing the internal electric field.
C) Allow current to flow through the plates.
D) Make the capacitor smaller.
