A simple pendulum has time period T(1). ...

A simple pendulum has time period `T_(1)`. The point of suspension is now moved upward according to the relation `y= kt^(2)(k=1 ms^(-2))` where y is the vertical diplacement. The time period now becomes `T_(2)`. What is the ration `(T_(1)^(2))/(T_(2)^(2))` ? Given `g=10 ms^(-2)`
