A coin placed on a gramophone record at `100//3` rpm flies off when it is place at a distance grater than 16 cm from the axis of rotation. If the record is rotating at `200//3`

A coin placed on a gramophone record rotating 100/3 rpm flies off when it is placed at a distance greater than 16 cm from the axis of rotation, if the gramophone record is rotating at 200/3 then its distance from the axis of rotation is

A small objective placed on a rotating horizontal trun table just slip when it is placed at a distance 4cm from the axis of rotation. If the angular velocity of the trun-table doubled, the objective slip when its distance from the axis of ratation is.

A small objective placed on a rotating horizontal turn table just slips when it is placed at a distance 4cm from the axis of rotation. If the angular velocity of the trun-table doubled, the objective slip when its distance from the axis of ratation is.

A coin placed on a rotating gramophone disc, remains at rest when it is at a distance of 9 cm from its centre ,the angular velocity of the disc is then tripled .At what distance from the centre ,the coin should be placed , so that it will remain at rest ?

A coin placed on a rotating turntable just slips if it is placed at a distance of 16 cm from the centre. If the angular velocity of the turnable is doubled, it will just slip at a distance ( in cm) of

A coin just remains on a disc rotating at 120 r.p.m. when kept at the distance of 1.5 cm from the axis of rotation. Find the coefficient of friction between the coin and the disc.
