The strings AB and AC each of length 40 cm , connect a ball of mass 200 g to a vertical shaft as shown. When the shaft rotates at a constant angular speed $\omega$, the ball travels in a horizontal circle with the strings inclined at $\gamma=30^{{}^{{}^{\circ}}}$ to the shaft. If the tension in the string AC is 4 N , that in the string AB and the angular speed $\omega$ respectively, are
