In contrast to the attractive force between two objects with opposite charges, two objects that are of like charge will repel each other. That is, a positively charged object will exert a repulsive force upon a second positively charged object.
In respect to this, what do you think will happen when molecules with the same charges interact?
Molecules with the same charge will repel each other as they come closer together while molecules with opposite charges will attract.
Secondly, what happens when charges are brought together?
Two charged objects will: repel each other if they have like charges (they are both positive or both negative) attract each other if they have opposite charges (one is positive and the other is negative)
Why do charged particles interact with each other?
An electric field is a space surrounding a charged particle where the particle exerts electric force. When charged particles are close enough to exert force on each other, their electric fields interact. Particles with opposite charges attract each other.
Why does the same charge repel each other?
The two charges repel each other. If a positive charge and a negative charge interact, their forces act in the same direction, from the positive to the negative charge. As a result opposite charges attract each other: The electric field and resulting forces produced by two electrical charges of opposite polarity.
