A bead B is threaded on a smooth circular wire frame of radius r , the radius vector r making an angle T with the negative z-axis (see Fig. 3.3). If the frame is rotated with angular velocity w about the z-axis then show that the bead will be in equilibrium if w = w=sqrt(g/cosT)

Solution:
A bead B is threaded on a smooth circular wire frame of radius r , the radius ve
