comment Which one of the following is true for all vectors $u$, $v$ and $w$ where $u\cdot v = 0$ and $u\cdot w = 0$?
I think the question I originally answered for a) is actually more interesting as it's a common misconception that two vectors that dot with a third to zero must be parallel to each other.

Hi @Daryl. I misread the question... $u$ looks like $v$, I'll edit!
