The correct answer is "αντιστρόφως ανάλογο του τετραγώνου της μεταξύ τους απόσταση, ανάλογο του γινομένου των φορτίων τους". This means that the force between two charges is inversely proportional to the square of the distance between them and directly proportional to the product of their charges. This is known as Coulomb's law, which describes the electrostatic force between charged objects.
