Limiting (i.e., maximum) static friction is slightly less than sliding friction.

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.

Assertion: Magnitude of the contact force is always greater than the magnitude of frictional force. Reason: Contact force is the resultant of the friction force and normal reaction.

Choose the correct statements – (1) Kinetic friction is lesser than limiting friction. (2) In rolling the surfaces at contact do not rub each other. (3) If a body is at rest and no pulling force is acting on it, force of friction on it is zero. (4) Kinetic friction is greater than limiting friction.

STATEMENT-1: During a turn, the value of centripetal force should be less than the limiting frictional force. STATEMENT-2: The centripetal force is provided by the frictional force between the tyre and the road.

Assertion :- When a man climbs the rope friction force acts in downward direction. Reason :- Friction force opposes relative motion ot tendency of relative motion between two contact surfaces.

Assertion : Resistance of an ammeter is less than the resistance of a milliammeter. Reason : Value of shunt required in case of ammeter is more than a milliammeter.

(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 .
