A block kept on a rough surface starts sliding when the inclination of the surface is with respect to the horizontal. The coefficient of static friction between the block and the surface is

Correct answer

2

Step-by-step solution

As the block starts stipping for angle of inclination , it must be equal to angle of repose given by aligned &= ⁻¹ _ s or _ s &= aligned
