At a certain height a shell at rest explodes into two equal fragments.

1.	At a certain height a shell at rest explodes into two equal fragments. One of the fragments receives a horizontal velocity u. The time interval after which, the velocity vectors will be inclined at 120^(@) to each other is
Answer» `(u)/(SQRT(3)g)` `(sqrt(3)u)/(g)` `(2u)/(sqrt(3)g)` `(u)/(2sqrt(3)g)` ANSWER :A
