Time period of a simple pendulum at geometric centre is given as infinite in all the books I have read.. Though dat is very illogical given dat t=2pi*sqrt(l/g) where g is zero where anything upon zero is UNDEFINED not infinite,( undefined = both positive and negative infinite)

But for the case when pendulum's oscillation in free fall the pendulum stays at absolute rest without any restoration force implying no shm at all so how can the time period be infinte for something not even oscillating

Also given a choice, zero is a far more logical alternative than undefined however for dat frequency wud be undefined

If anybody can please explain the doubt and where I am going wrong as fad as logical bit is concerned

Thanks :)
