I'm not sure if you made a typo or not but in the current context I can only see negligible being relevant.
It is directly proportional to the charges in the particles and inverses proportional to the square of the distance between them
Andrew Jackson won redemption four years later in an election that was characterized to an unusual degree by negative personal attacks. Jackson and his wife were accused of adultery on the basis that Rachel had not been legally divorced from her first husband when she married Jackson. Shortly after his victory in 1828, the shy and pious Rachel died at the Hermitage; Jackson apparently believed the negative attacks had hastened her death. The Jacksons did not have any children but were close to their nephews and nieces, and one niece, Emily Donelson, would serve as Jackson’s hostess in the White House.
