Equilibrium in electric force occurs when the net electric force on an object is equal to zero, meaning that the object is not experiencing any acceleration or movement due to electric forces.
Equilibrium in electric force can be achieved by either balancing out the forces acting on an object or by canceling out the individual forces.
The conditions for equilibrium in electric force are that the net electric force must be equal to zero and the electric field must be uniform.
In stable equilibrium, the object returns to its original position after being slightly displaced, while in unstable equilibrium, the object moves away from its original position when slightly displaced.
The distance between charged objects affects equilibrium in electric force by altering the strength of the electric force. As the distance between objects increases, the electric force decreases, potentially leading to a state of equilibrium.
