This study guide covers electromagnetism, focusing on electric fields and forces. It reviews Coulomb's Law and its application to calculating electrostatic forces between point charges. The guide explains electric fields, including how to draw and interpret field lines for various charge configurations (point charges, parallel plates). It also covers electric field strength calculations and vector addition for forces and fields. Finally, practice questions and exam tips are provided to help students prepare for the AP Physics 2 exam.

#AP Physics 2: Unit 5 - Electromagnetism 🧲

Welcome to your ultimate Unit 5 study guide! This unit dives into the fascinating world of electromagnetism, a cornerstone of modern technology. Let's get started!

This unit constitutes approximately 10% of the AP exam, so it's crucial to master these concepts. Focus on understanding the relationships between electric and magnetic fields, and their applications.

#Electric Fields & Forces 🧙

This section builds upon concepts from Unit 3, particularly Coulomb's Law. If you need a refresher, revisit that material before proceeding.

#Electrostatic Force & Coulomb's Law

Coulomb's Law quantifies the force between two point charges:

$F = k \frac{|q_1 q_2|}{r^2}$

Where:

$F$ is the electrostatic force
$k$ is Coulomb's constant
$q_1$ and $q_2$ are the magnitudes of the charges
$r$ is the distance between the charges

Key Concept

Remember that like charges repel, and opposite charges attract. A positive force indicates repulsion, and a negative force indicates attraction.

Memory Aid

"Opposites Attract, Likes Repel" - A simple phrase to remember the direction of electrostatic forces.

Electrostatic force is a fundamental force that governs the interactions of charged particles.
Coulomb's Law is the mathematical expression of this force.

Exam Tip

Don't forget that electrostatic force is a vector! Use vector addition to find the net force when multiple charges are present.

#Electric Fields

Every charged object creates an electric field around it. The field exerts a force on any other charge placed within it. Electric fields are represented by field lines, which are vectors that indicate the direction of the force on a positive test charge.

Key Rules for Drawing Electric Fields:

Field lines originate from positive charges and terminate at negative charges.
Field lines are always per...
