उत्तर
There is always attraction when opposite electric charge come near each other.
Explanation:
This happens because opposite charges (positive and negative) attract each other due to the fundamental electrostatic force described by Coulomb's law. Positive charges attract negative charges and vice versa, while like charges repel each other. This is why opposite charges always experience an attractive force when they come near each other.
