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