Question

which particles have the strongest repulsion?

Explanation:

Like - charged particles repel each other. The closer they are, the stronger the repulsion. Among the options, the two negative charges that are closest together (bottom - right) experience the strongest repulsion as per Coulomb's law which states that the electrostatic force between two charged particles is directly proportional to the product of their charges and inversely proportional to the square of the distance between them.

Answer:

The two negative particles that are closest together (bottom - right)
