A body takes ''n'' times as much time to slide down a rough inclined plane as it takes to slide down an identical but smooth inclined plane. If the angle of inclination of the inclined plane is ''theta'' . What is the coefficient of friction between the body and the rough plane ?

If the angle of inclination of the inclined plane is sin^(-1) ((1)/(2)) when the body just starts sliding find the angle of repose and coefficient of static friction between the body and the inclined plane.
