Circular Dynamics....
Two particles of mass M = 3 kg each are kept on a horizontal circular platform on two mutually perpendicular radii at equal distance R = 1 m from the centre of the table. The particles are connected with a string, which is just taught when the platform is not rotating. Coefficient of friction between the platform and block is = 0.1. Then the maximum angular speed ( in rad/sec) of platform about its centre so that the blocks remain stationary relative to platform. (take g = 10 m/s^2)
The answer is 1.
