JEE Mains (Friction)

The minimum force required to start pushing a body up a rough (frictional coefficient μ) inclined plane F₁ while the minimum force needed to prevent it from sliding down is F₂. If the inclined plane makes an angle θ from the horizontal such that tan θ= 2μ then the ratio F₁/F₂ is

(a) 4

(b) 1
