Physics - Circular Motion Question with Solution | TestHub

A very small cube of mass $2kg$ is placed on the surface of a funnel as shown in the figure. The funnel is rotating about its vertical axis of symmetry with angular velocity $\omega$. The wall of the funnel makes an angle $37^{\circ }$ with the horizontal. The distance of the cube from the axis of rotation is $20cm$, and the frictional coefficient is $\mu$. (Take $g=10m/s^2$)
