Coulomb’s Law
Coulomb’s Law, named after the French physicist Charles-Augustin de Coulomb, is a fundamental law in electrostatics that describes the force of interaction between two point charges.
According to Coulomb’s Law, the electrostatic force between two point charges is directly proportional to the product of the charges and inversely proportional to the square of the distance between them.
Formula
The mathematical formula for Coulomb’s Law is given by:
F = k
- (q1
- q2) / r^2
where:
- F is the electrostatic force between the charges (in newtons)
- k is Coulomb’s constant (8.98755 × 10^9 N⋅m^2/C^2)
- q1 and q2 are the charges of the particles (in coulombs)
- r is the distance between the charges (in meters)
Applications of Coulomb’s Law
Coulomb’s Law finds applications in various fields, including physics, engineering, and chemistry:
Electric Fields
Coulomb’s Law is used to calculate the electric field created by a point charge. The electric field is a vector quantity that describes the force experienced by a unit charge at a given point in space.
Capacitors
Coulomb’s Law is used to design and analyze capacitors. Capacitors are devices that store electrical energy by separating opposite charges on two conductors.
Atomic Structure
Coulomb’s Law helps explain the electrostatic interactions between electrons and protons within an atom. These interactions determine the structure and stability of atoms.
Factors Affecting Coulomb’s Law
The strength of the electrostatic force between charged particles is influenced by several factors:
Distance
The force between charges decreases as the distance between them increases. This inverse square relationship is a fundamental characteristic of Coulomb’s Law.
Charge Magnitude
The force between charges is directly proportional to the magnitude of the charges. Charges with larger magnitudes experience stronger forces.
Medium
The force between charges can be affected by the medium in which they are located. For example, the force is weaker in a dielectric medium than in a vacuum.
| Factor | Impact on Force |
|---|---|
| Distance (r) | Decreases as r^2 increases |
| Charge Magnitude (q1, q2) | Increases as q1 and q2 increase |
| Medium | Weaker in dielectrics |
