Questions
A body is sliding down an inclined plane having coefficient of friction 0.5. If the normal reaction is twice that of the resultant downward force along the incline, the angle between the inclined plane and the horizontal is
detailed solution
Correct option is C
Normal reaction on the inclined plane is μmgcosθ and resultant downward force mg(sinθ−μcosθ)Given, mgcosθ=2[mg(sinθ−μcosθ)]Solving by putting μ=0.5,θ=45∘Talk to our academic expert!
