Question

Select One Option Correct from the following : A simple pendulum has time period $T_1$. The point of suspension is now moved upwards according to the relation $y = kt^{2} , (k = 1 m/s^{2})$ where y is the vertical displacement. The time period now becomes $T_2$. The ratio of $T^{2} _1/T^{2} _2$ is [Take $g = 10 m/s^{2}$.]
