A) Angle of repose is equal to angle of friction
B) Angle of friction is independent of coefficient of friction
detailed solution
Correct option is D
If the block is the verge of slipping , we can write - mg sinθ = fBut N = mg cosθ and f = μs .N.: mg sinθ = μs .mg cosθ ⇒ θ = tan-1(μs) = λSimilar Questions
