To maximize the electric force between two charges, they must have the same sign. According to Coulomb's law, the electric force
between two point charges is given by:
where
is Coulomb's constant,
and
are the magnitudes of the charges, and
is the distance between the charges.For the force to be maximized, the product
should be maximized. This occurs when both charges are either both positive or both negative.Therefore, the charges must be:
