A coins kept on a horizontal rotating disc has its centre at a distance of 0.25 m from the axis of rotation of the disc .If `mu is 0.2`, then the angular velocity of the disc at which the coion will slip off, `(g=9.8m//s^(2))`

A coin kept on a horizontal rotating disc has its centre at a distance of 0.25 m from the axis of rotation of the disc. If mu is 0.2, then the angular velocity of the disc at which the coin willslip off, is

A coin kept on a horizontal rotating disc has its Centre at a distance of 0.1 m from the axis of the rotation of the disc. If the coefficient of friction between the coin and disc is 0.25, find the angular speed of the disc at which the coin would be about is slip off.

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.

A coin kept on a rotating gramophone disc just beging to slip if its centre is at a distance of 8 cm from the centre of the disc .The angular velocity of the gramophone disc is then doubled , Through what distance , the coin should be shifted towards the centre , so that the coin will just slip ?

A small coin is kept at the rim of a horizontal circular disc which is set into rotation about verticle axis passing through its centre. If radius of the disc is 5 cm and mu_(s)=0.25 , then the angular speed at which the coin will just slip off at

A coin placed on a horizontal rotating disc, with its centre at 10 cm from the centre of the disc, is about to slip off when the disc performs 60 rpm. Find the coefficient of friction between the coin and the disc.

A body is kept on a horizontal disc of radius 2 m at a distance of 1 m from the centre . The coefficient of friction between the body and the surface of disc is 0.4. The speed of rotation of the disc at which the body starts slipping is (g=10 m//s^2 )
