Answer: Option (C) is the correct answer.
Explanation:
Electrostatic force of attraction is defined as the force which exists between the species that are electrically charged that is, species that contain a positive or negative charge.
Whereas when two species have similar charge then they tend to oppose or repel each other. This is because opposite charges repel each other.
And, opposite charges attract each other. Hence, strong electrostatic force of attraction exists between them.
For example, [tex]Cs^{+}[/tex] and [tex]N^{-}_{3}[/tex] species have opposite charges and when both of them come in contact with each other then strong electrostatic force of attraction exists between them.
Thus, we can conclude that [tex]Cs^{+}[/tex] and [tex]N^{-}_{3}[/tex] would have an electrostatic force of attraction between them.
