Verified Answer
A block is resting on an incline plane. The block just starts slippin...
As the block is at rest, these forces should add up to zero. Also, since 0 is the maximum angle to prevent slipping, this is a case of limiting equilibrium and so f = μsN
f = mg sin θ
N = mg cos θ
∴ tan θ = f/N = μs
So μs = tan 30° = 1/√3
