Problem

A block just begins to slide down a rough plane when the plane is inclined at an angle θ\theta to the horizontal. Which relation gives the coefficient of static friction μs\mu_s between the block and the plane? a) μs=sin⁡θ\mu_s = \sin \theta b) μs=cos⁡θ\mu_s = \cos \theta c) μs=tan⁡θ\mu_s = \tan \theta d) μs=cot⁡θ\mu_s = \cot \theta
