vec a,vec b,vec c are three non zero vectors no two of which are collonear and the vectors vec a+vec b be collinear with vec c,vec b+vec c to collinear with vec a then vec a+vec b+vec c the equal to ?(A)vec a (B) vec b(C)vec c (D) None of these

If vec a,vec b and vec c are three non-zero vectors,no two of which ar collinear,vec a+2vec b is collinear with vec c and vec b+3vec c is collinear with vec a then find the value of |vec a+2vec b+6vec c|

If vec a , vec b and vec c are three non-zero vectors, no two of which are collinear, vec a+2 vec b is collinear with vec c and vec b+3 vec c is collinear with vec a , then find the value of | vec a+2 vec b+6 vec c| .

If vec a , vec b and vec c are three non-zero vectors, no two of which are collinear, vec a+2 vec b is collinear with vec c and vec b+3 vec c is collinear with vec a , then find the value of | vec a+2 vec b+6 vec c| .

Let vec a,vec b and vec c be three non-zero vectors, no two of which are collinear.If the vector 3vec a+7vec b is collinear with vec c and 3vec b+2vec c is collinear with bar(a), then 9vec a+21vec b+14vec c is equal to.

If vec a , vec ba n d vec c are three non-zero vectors, no two of which ar collinear, vec a+2 vec b is collinear with vec c and vec b+3 vec c is collinear with vec a , then find the value of | vec a+2 vec b+6 vec c|dot

Let vec a, vec b and vec c be three non zero vectors such that no two of these are collinear. If the vector vec a + 2 vec b is collinear with vec c and vec b + 3 vec c is collinear with vec a then vec a + 2 vec b + 6 vec c =
