[" (ii) The minimum angle made by the inclined plane with the horizontal surface such that the "],[" body lying on it just begins to slide down is called "]

The angle which the rough inclined plane makes with the horizontal when the body placed on it just starts sliding down is called .

The angle of inclined plane with the horizontal such that an object placed on it begins to slide is

The angle which the rough inclined plane makes with the horizontal when the body placed on it just starts sliding down is called

The angle which the rough inclined plane makes with the horizontal when the body placed on it just starts sliding down is called

Assertion: A body slides down an inclined plane if the angle of friction is more than the angle of the inclined plane with the horizontal. Reason : When the angle of inclination is equal to the angle of friction, the component of weight parallel to the plane is just sufficient to overcome the frictional force.
