Electrostatic force

Definition

Electrostatic force is the force of attraction or repulsion between electrically charged objects. It follows Coulomb's Law, which states that the force is inversely proportional to the square of the distance between charges and directly proportional to the product of the charges.

5 Must Know Facts For Your Next Test

1. Electrostatic force can be both attractive and repulsive depending on the nature of the charges involved.
2. The magnitude of electrostatic force decreases with the square of the distance between two charges.
3. Coulomb's Law mathematically defines electrostatic force: $F = k \frac{q_1 q_2}{r^2}$, where $k$ is Coulomb's constant, $q_1$ and $q_2$ are charges, and $r$ is the distance between them.
4. Like charges repel each other while opposite charges attract each other.
5. Electrostatic forces are central in determining molecular structures and interactions.
