    What is done to increase friction between the tyres and road ?

    A : During horizontal circular turn of a car, the centripetal force required should be less than the limiting friction between its tyres and road. R : The centripetal force to car is provided by the frictional force between its tyres and the road.

    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 : A cyclist bends inwards from his ver- tical position, while turning to secure the necessary centripetal force. Reason : Friction between the tyres and road pro- vides him the necessary centripetal force.

    When a vehicle is moving along the horizontal curve road, centripetal force is provided by
