A gramophone disc rotates at 60 rpm . A coin of mass 18 g is placed at a distance of 8 cm from the centre . Calculate centrifugal force on the coin . Take pi^(2) = 9. 87 .

A gramophone disc rotates at 60 revolutions per minute. A coin of mass 13 g is placed at the disc at a distance of 8.0 cm from the centre. Calculate centrifugal force on the coin.

A circular disc rotates at 60 rpm about an axis passing through its centre. A coin of 18 g is placed at a distance of 8 cm from the centre of the disc. Calculate the centrifugal force on the coin.

A gramophone disc rotates with a uniform angular velocity of 6 rad//s . A coins of mass 2 gm is placed 5 cm from the centre .The centripetal force acting on the coin is

A disc starts rotating with a constant angular acceleration of 1 rad//s^(2) about a fixed vertical axis perpendicular to its plane and passing through its centre. A coin of mass 10 gm is placed on the disc at a distance of 10cm from the axis. The coefficent of friction between the disc and the coin is 0.2 . The value of the frictional force on the coin at t=1s will be
