Let the vectors vec(PQ),vec(QR),vec(RS),vec(ST),vec(TU) and vec(UP) represent the sides of a regular hexagon. Statement 1: vec(PQ)xx(vec(RS)+vec(ST))!=vec0 Statement 2: vec(PQ)xxvec(RS)=vec0 and vec(PQ)xxvec(ST)!=vec0

Solution :Clearly, `vec(RS)+vec(ST)=vec(RT)` which is not parallel to `vec(PQ)`
`:.vec(PQ)XX(vec(RS)+vec(ST))!=vec0`
So STATEMENT-1 is TRUE.
Also, `vec(PQ)` is not parallel to `vec(RS)`

`:.PQxxvec(RS)!=vec0`
So, statement -2 is not true.
