An object placed on an inclined plane starts sliding when the angle of incline becomes `30^(@)` the coefficent of statyic friction between the object and the plane is

A box is lying on an inclined plane if the box slides when the angle of inclination is 60^(@) then the coefficient of static friction of the box and the plane is?

A block is at rest on an inclined plane making an angle alpha with the horizontal . As the angle alpha of the incline is increased the block starts slipping when the angle of inclination becomes theta . The coefficient of static friction between the block and the surface of the inclined plane is or A body starts sliding down at an angle theta to the horizontal. Then the coefficient of friction is equal to

A given object taken n time more time to slide down 45^(@) rough inclined plane as it taken to slide down a perfectly smooth 45^(@) incline The coefficient of kintic friction between the object and the incline is .

A given object taken n time more time to slide down 45^(@) rough inclined plane as it taken to slide down a perfectly smooth 45^(@) incline The coefficient of kintic friction between the object and the incline is .

A 20kg box is gently placed on a rough inclined plane of inclination 30^(@) with horizontal. The coefficient of sliding friction between the box and the plane is 0.5.Find the acceleration of the box down the incline.

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.
