this answer is a little visual rather than mathematical
u know that the cross product of two vectors is a vector which is perpendicular to both the vectors. So (v x u) is perpendicular to u and also v. And then the angle between (v x u) and u is 90°
so the dot product u.(v x u) is zero

???
This makes no sense as stated.
You can only cross 2 vectors, not a scalar and a vector.
There is no such thing as the cross product of u.
It has to be be crossed with another vector.
If you mean u crossed with itself then the answer is 0.
