A small coin is placed on a flat horizontal turn table. The turn table is observed to make three revolutions in 3.14 sec . What is the coefficient of static friction between the coin and turn table if the coin is observed to slide off the turn table when it is greater than 10cm from the centre of turn table .

The road at a circular turn of radius 10 m is banked by an angle of 10^0 . With what speed should a vehicle move on the turn so that the normal contact force is able to provide the necessary centripetal force?

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.

Assertion: The artifical satellite does not have any fuel but even then it remains orbiting around the earth. Reason: The necessary centripetal force required to move the satellite in an ·orbit around the earth is provided by the gravitational force of attraction between the satellite and the earth.
