Maximum force of friction is called

Assertion : Friction always opposes the motion. Reason : Whenever one surface moves or tries to move over another surface, the force of friction starts acting on the surfaces.

Assertion : Angle of repose is equal to angle of limiting friction. Reason : When the body is just at the point of motion, the force of friction in this stage is called as limiting friction.

When a body moves on a circular path, the force that acts on the revolving body towards the center is called :

(A) : If a body is trying to slip over a surface then friction acting on the body is necessarily equal to the limiting friction . (R) : Static friction can be less than the limiting friction force .
