A heavy box is to be dragged along a rough horizontal floor. To do so, person A pushes it at an angle `30^(@)` from the horizontal and requires a minimum force `F_(A)`, while person B pulls the box at angle `60^(@)` from the horizontal and needs minimum force `F_(B)`. If the coefficient of friction between the box and the floor is `sqrt(3)/(5)` , the ratio is `(F_(A))/(F_(B))`
