A given object takes n times the time to slide down $\displaystyle 45^{\circ}$ rough inclined plane as it takes the time to slide down an identical perfectly smooth $\displaystyle 45^{\circ}$ inclined plane. The coefficient of kinetic friction between the object and the surface of inclined plane is:
