Physics - Circular Motion Question with Solution | TestHub

Figure shows a rod arranged at an angle of 30° from the horizontal attached to the two strings is the mass m as shown. The rod is rotated maintaining its direction in space, so that m travels in a circular path. The strings are of equal length and make angle of 60° with the rod as shown. Calculate the minimum value of the tangential speed (m/sec) of the mass such that the string with tension ${\mathrm{T}}_2$ does not become slack when the mass is directly above rod. Take length of string as $\ell =2.4\mathrm{m}$
