Question

The minimum number of non zero non collinear vectors required to produce a zero vector is

Answer 1

Explanation:

3 vectors represented by 3 sides of triangle taken in the same order

Answer 2

$\huge\underbrace\mathfrak\pink{Answer}$

three

So you need more vectors. So u,v,w are non collinear and sum up to zero vector. More than three vectors are not necessary.
