When a body slides down from rest along a smooth inclined plane making an angle 30 0 of with the horizontal, it takes time T. When the same body slides down from the rest along a rough inclined plane making the same angle and through the same distance, it takes time 
, where 
is a constant greater than 1. The co-efficient of friction between the body and the rough plane is 
where x =......
