Answer:
The minimum force required to start pushing a body up a rough inclined plane is
F
1
=mgsinθ+μgcosθ ......(i)
Minimum force needed to prevent the body from sliding down the inclined plane is
F
2
=mgsinθ−μgcosθ ...........(ii)
Divide (i) by (ii), we get
F
2
F
1
=
sinθ−μcosθ
sinθ+μcosθ
=
tanθ−μ
tanθ+μ
=
2μ−μ
2μ+μ
=3 (tanθ=2μ
