The electrical force is a fundamental force of nature that is responsible for the attraction or repulsion of electrically charged particles. It is one of the four fundamental forces, along with gravity, strong nuclear force, and weak nuclear force.

Key Concepts

Electric Charge: Electric charge is a fundamental property of matter that can be positive or negative. Like charges repel each other, and opposite charges attract each other.
Coulomb's Law: Coulomb's law describes the magnitude of the force between two charged objects. The force is directly proportional to the product of the charges and inversely proportional to the square of the distance between them.
Electric Field: An electric field is a region of space around a charged object where another charged object experiences a force. The direction of the electric field is the direction of the force that a positive test charge would experience if placed in the field.
Electric Force and Work: The electric force can do work on charged objects, causing them to move and gain kinetic energy. The work done by the electric force is equal to the change in potential energy of the charged object.
