0When the string of a conical pendulum makes an angle of \( 45^{\circ} \) with the vertical, its time period is \( T_{1} \). When the string makes an angle of \( 60^{\circ} \) with the vertical, its time period is \( T_{2} \). Then \( T_{1}^{2} / T_{2}^{2} \) is
(1) 2
(2) \( \sqrt{2} \)
(3) \( 0.5 \)
(4) none of these
