Two identical simple pendulums A and B are fixed at same point. They are displaced by very small angles `alpha` and `beta ( beta gt alpha)` and released from rest. Find the time after which B reaches its initial position for the first time. Collisions are elastic and length of strings is `l`.

A

`pi sqrt((l)/(g))`

B

`2pi sqrt((l)/(g))`

C

`(pi beta)/(alpha) sqrt((l)/(g))`

D

`(2pi beta)/(alpha) sqrt((l)/(g))`
