Electrostatics, a crucial branch of physics, deals with the study of forces between charged particles. To truly understand these forces, it’s essential to dive into the precision of Coulomb’s Law, which describes the interaction between electrically charged particles. One of the primary tools for this purpose is the Coulomb’s Law Apparatus.
Understanding Coulomb’s Law
Coulomb’s Law provides a mathematical framework for predicting the nature and magnitude of forces between charges. This foundational principle is comparable to Newton’s Law of Universal Gravitation but for electric charges.
- Force (F): Directly proportional to the product of the magnitudes of charges.
- Distance (r): Inversely proportional to the square of the distance between the charges.
- Constant (k): Dependent on the medium surrounding the charges.
