The magnitude of the electrical charge on objects directly affects the electric force between them. According to Coulomb's Law, the electric force between two charged objects is directly proportional to the product of their charges and inversely proportional to the square of the distance between them. Therefore, the greater the magnitude of the electrical charge on the objects, the greater the electric force between them will be. In other words, objects with larger charges will exert a stronger force on each other than objects with smaller charges.
