Final answer:
To achieve the greatest force, you should split the charge unevenly. This is because the force between two charges is inversely proportional to the squared distance between them, according to Coulomb's law.
Step-by-step explanation:
To achieve the greatest force, you should split the charge unevenly. This is because the force between two charges is inversely proportional to the squared distance between them, according to Coulomb's law. So, if you split the charge unevenly and have one charge closer to the other, you will maximize the force.
