A small coin of mass 5 g is placed at a distance 5 cm from centre on a flat horizontal turn table. The turn table is observed to make 3 revolutions in `sqrt(10)s`. The frictional force on the coin is `(n xx 10^(-3)) N`. Find value of `n`.

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 .

A coin is place at a distance 9 cm from centre on a rotating turn table slip. If the angular velocity of the turn table is tripled, then the distance ofn the coin from the centre will be

A coin is placed at a distance 9 cm from centre on a rotating from table starts slip. If the angular velocity of the turn table is tripled , then the distance of the coin from the centre will be

A coin is kept at distance of 10 cm from the centre of a circular turn table. If mu=0.8 the frequency of rotation at which the coin just begins to slip is

A coin is kept at distance of 10 cm from the centre of a circular turn table. If mu=0.8 the frequency of rotation at which the coin just begins to slip is

A coin placed on a rotating turn table just slips if it is placed at a distance of 8 cm from the centre. If angular velocity of the turn table is doubled . It will just slip at a distance of
