The minimum force required to start push...

The minimum force required to start pushing a body up a rough (frictional coefficient `mu`) inclined plane is `F_(1)` while the minimum force needed to prevent it from sliding down is `F_(2)`. If the inclined plane makes an angle `theta` with the horizontal such that `tan theta =2mu` then the ratio `(F_(1))/(F_(2))` is .
