A simple pendulum doing small oscillations at a place R height above earth surface has time period of T1 = 4 s. T2 would be it's time period if it is brought to a point which is at a height 2R from earth surface. Choose the correct relation [R = radius of Earth]:
1
T1 = T2
2
2T1 = 3T2
3
3T1 = 2T2
4
2T1 = T2
