Question
A body is plane on an inclined plane. The coefficient of friction between the body and the plane is μ.
The plane is gradually tilted up. If θ is the inclination of the plane frictional force on the body is
The plane is gradually tilted up. If θ is the inclination of the plane frictional force on the body is
Options
A.Constant up to = tan1(μ) and decreases after the
B.Increases up to = tan1(μ) and decreases after the
C.decreases up to = tan1(μ) and constant after the
D.Constant throughout
Solution
friction force F = mg sin θ if ≤ tan (μ) and F = μmg cos θ if θ ≥ tan-1(μ)
Which increases upto θ = tan-1(μ) and then decreases.
Which increases upto θ = tan-1(μ) and then decreases.
