In case i wedge B is stationary and block A starts sliding when the angle of plane is greater than a certain value `theta`. While in case ii wedge B is moving upwards with an accelration `a_(0)` and the block A starts sliding when the angle of plane is greater than `alpha`. Coeffiecient of friction between A and B in both the cases is same. then .

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 block is at rest on an inclined plane making an angle alpha with the horizontal. As the angle of the incline is increased the block start slipping when the angle of inclination becomes theta then coefficient of friction is equal to

A block is at rest on an inclined plane making an angle alpha with the horizontal. As the angle of the incline is increased the block start slipping when the angle of inclination becomes theta then coefficient of friction is equal to

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.

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

Prove that the horizontal range is same when angle of projection is (i) greater than 45^(@) by certain value and (ii) less than 45^(@) by the same value.
