Question
A pendulum isA pendulum is suspended in a lift and its period of oscillation when the lift is stationary is T0. What must be the acceleration of the lift so that the period of oscillation of the pendulum to be T0/2 ?
Options
A.2g downward
B.2g upward
C.3g downward
D.3g upward
Solution
T0 = 
.....(i)
Now
..........(ii)
⇒
= 4 ⇒ a = 3g (upwards)
