P. 4167. A 1-kg object is placed to an inclined plane of variable slope angle. The object begins to slide down when the slope angle is =20o. If the slope angle is adjusted to =10o, what is the magnitude of the force F which makes the body slide, if force F lies in the plane of the incline and is perpendicular to the direction of the slope. In which direction does the object slide?
