A body takes `1(1)/(3)` 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 is `45^(@)` find the coefficient of friction.

A block takes a twice as much time to slide down a 45^(@) rough inclined plane as it takes to slide down a similar smooth , plane . The coefficient of friction is :

A given object takes n times as much time to slido down a 45^(@) rough inclined plane as it takes to slide down a perfectly smooth 45^(@) inclined plane. The coefficient of kinetic friction between the object and the inclined plane is given by:

A body takes n times as much time to slide down a 45^@ rough incline as it takes to slide down a smooth 45^@ incline. The coefficient of friction between the body and the incline will be

A given object takes 3 times as much time to slide downa 45° rough incline as it takes to slide down a perfectly smooth 45° incline. The coefficient of friction between the object and the incline is :

A block slides down on inclined plane (angle of inclination 60^(@) ) with an accelration g//2 Find the coefficient friction

A given object takes m times as much time to slide down a 45^(@) rough incline as it takes to slide down a perfectly smooth 45^(@) incline. The coefficient friction between the objected and the incline is given by
