Three equal charges are placed on the three corners of a square. If the force between `q_(1)` and `q_(2)` is `F_(12)` and that between `q_(1)` and `q_(3)` is `F_(13)`, then the ratio of magnitudes `(F_(12)//F_(13))` is

Three equal charges are placed at the three corners ABC of a square ABCD. If the force between the charges at A&B ("on" q_(1) and q_(2)) is F_(12) and that between q_(1) and q_(3) is F_(13) the ratio of magnitudes F_(12)//F_(13) is _____
