An object initially at rest explodes into three fragments `A, B` and `C`. The momentum of `A` is `phati` and that of `B` is `sqrt(3)phatj`
where `p` is `a +ve` number. The momentum of `C` will be

A

`(1+sqrt(3))p` in a direction making angle `120^(@)` with that of `A`

B

`(1+sqrt(3))p` in a direction making angle `150^(@)` with that of `B`

C

`2p` in as direction making angle `150^(@)` with that `A`

D

`2p` in a direction making angle `150^(@)` with that of `B`.
