Coulombic attraction is a fundamental concept in the realm of physics and chemistry that describes the force of attraction between charged particles. Understanding this concept is essential for students, as it plays a significant role in various applications such as ionic bonds, electrostatic interactions, and molecular structures. To help master this concept, we have created a comprehensive Coulombic attraction worksheet that simplifies the idea and provides practical exercises. Let’s dive into the details!
What is Coulombic Attraction? ⚡
Coulombic attraction refers to the attractive force between two oppositely charged particles. Named after the French physicist Charles-Augustin de Coulomb, this principle explains how and why charged objects exert forces on each other.
Key Characteristics of Coulombic Attraction
-
Charge Interaction: The force of attraction increases with the magnitude of the charges. The more significant the charges, the stronger the attraction.
-
Distance Dependence: The force decreases with the square of the distance between the charges. This means that as the distance increases, the force diminishes rapidly.
-
Mathematical Expression: Coulomb's Law mathematically expresses this relationship as follows:
[ F = k \cdot \frac{|q_1 \cdot q_2|}{r^2} ]
Where:
- ( F ) is the force of attraction or repulsion,
- ( k ) is Coulomb's constant ((8.99 \times 10^9 , N \cdot m^2/C^2)),
- ( q_1 ) and ( q_2 ) are the charges,
- ( r ) is the distance between the centers of the two charges.
Importance of Coulombic Attraction
Understanding Coulombic attraction is crucial for several reasons:
- It forms the foundation for ionic and covalent bonding in chemistry.
- It helps explain the behavior of atoms and molecules in various states.
- It plays a vital role in phenomena such as electricity and magnetism.
Coulombic Attraction Worksheet 📚

Given:
- ( q_1 = 2 \times 10^{-6} C )
- ( q_2 = -3 \times 10^{-6} C )
- ( r = 0.5 m )
Solution:
-
Substitute the values into Coulomb's Law formula:
[ F = k \cdot \frac{|q_1 \cdot q_2|}{r^2} ]
-
Calculate the force.
Exercise 2: Conceptual Questions
