A block is at rest on an inclined plane making an angle α with the horizontal. As the angle α of the incline is increased, the block starts slipping when the angle of inclination becomes θ. The coefficient of static friction between the block and the surface of the inclined plane is or A body starts sliding down at an angle θ to horizontal. Then coefficient of friction is equal to
Text Solution
Verified by ExpertsThe correct answer is:
C
Coefficient of friction = Tangent of angle of repose
µ = tan θ
