Answer:
Equilibrium occurs when opposite forces become balanced.
Step-by-step explanation:
In relation to charges:
Charges are said to be in equilibrium when the total net force is 0.
Net force is the sum of the forces acting on an object.
For example,
If, F1 = 16 and F2 = 2
the net force would be 18, not making it be in a state of equilibrium.
If, F1 = -1 and F2 = 1, the net force would be 0, making it be in a state of equilibrium.
