Two point charges are kept in air with certain separation between them.The force between them is F_(1) if half of the space between the charges is filled with a medium of dielectric constant 4 and the force between them is F_(2) if (1)/(3)rd of the space between the charges is filled with dielectric of dielectric constant 9.Then (F_(1))/(F_(2)) is
