A nucleus moving with a velocity `vecv` emits an `alpha`- particle. Let the velocities of the `alpha`- particle and the remaining nucleus be `vecv_1 and vecv_2` and their masses be `m_1 and m_2`. Choose correct statement.

A

all velocity vectors `vec(v) , vec(v)_1 and vec(v)_2` must be parallel

B

`vec(v)` must be parallel to `(vec(v)_1 +vec(v)_2)`

C

`vec(v)` must be parallel to `(m_1vec(v)_1 +m_2vec(v)_2)`
