A simple pendulum hanging from the ceiling of a stationary lift has a time period T1. When the lift moves downward with constant velocity, then the time period becomes T2. It can be concluded that: 

1. \(T_2 ~\text{is infinity} \) 2. \(\mathrm{T}_2>\mathrm{T}_1 \)
3. \(\mathrm{T}_2<\mathrm{T}_1 \) 4. \(T_2=T_1\)
