A simple pendulum has time period \( T_{1} \). The point of suspension is now moved upward according to the relation \( \mathrm{y}=\mathrm{Kt}^{2},\left(\mathrm{~K}=1 \mathrm{~m} / \mathrm{s}^{2}\right) \) where \( \mathrm{y} \) is the vertical displacement. The time period now becomes \( T_{2} \). The ratio of \( \frac{T_{1}^{2}}{T_{2}^{2}} \) is \( :\left(g=10 \mathrm{~m} / \mathrm{s}^{2}\right) \)
(1) \( \frac{6}{5} \)
(2) \( \frac{5}{6} \)
(3) 1
(4) \( \frac{4}{5} \)
