A pendulum is hanging from the ceiling of a cage . If the cage moves up with constant acceleration ‘a’ the tension is T1. If it moves down with the same acceleration ‘a’ then tension is T2. If the cage moves horizontally with the same acceleration ‘a’, then the tension is T in equilibrium w.r.t. cage. Then 2T^−2 is
