What must be the magnitude of static friction between the object and t

1.	What must be the magnitude of static friction between the object and thesurface if it does not start moving till the magnitude of applied force is greater than 4 N?
Answer» The MAGNITUDE of the frictional force is proportional to the normal force, fk = μkmg cosθ. The component of the net force down the slope is F = MG sinθ - μkmg cosθ. It is the vector sum of the frictional force and the tangential component of gravity. uh can watch YT videoes related to it ❤️
