There are two inclined surface of equal length (L) and same angle of inclination 
with the horizontal. One of them is rough and the other is perfectly smooth. A given body taken 2 times as much time to slide down on rough surface than on the smooth surface. The coefficient of kinetic friction 
between the object and the rough surface is close to
