Vedclass · Answer

(A) Limiting friction is the maximum value of static friction that acts when a body is just on the verge of motion.Once the body starts sliding,the contact surfaces do not have sufficient time to interlock completely.Due to this,the resistance offered by the surfaces decreases compared to the state of rest.Therefore,the force required to maintain motion (dynamic friction) is always less than the force required to initiate motion (limiting friction).Thus,limiting friction is always greater than dynamic friction.
