Coulombic Attraction: Definition and Overview: Coulombic Attraction Pogil Answer Key

Coulombic attraction is a fundamental force that describes the interaction between electrically charged particles. It is named after the French physicist Charles-Augustin de Coulomb, who first mathematically described the force in 1785. Coulombic attraction is a long-range force, meaning that it can act over large distances, and it is one of the four fundamental forces of nature, along with gravity, the weak force, and the strong force.

The strength of the Coulombic attraction between two charged particles is directly proportional to the magnitude of the charges and inversely proportional to the square of the distance between them. The mathematical formula for Coulombic attraction is:

F = k

• (q1
• q2) / r^2

where:

• F is the force of attraction
• k is Coulomb’s constant (8.98755 × 10^9 N⋅m^2/C^2)
• q1 and q2 are the magnitudes of the charges
• r is the distance between the charges

The sign of the force is positive if the charges are opposite (i.e., one positive and one negative) and negative if the charges are the same (i.e., both positive or both negative).

Q&A
