Homework Statement
Vectors [tex]\vec{A}[/tex], [tex]\vec{B}[/tex], and [tex]\vec{C}[/tex] satisy the vector equation [tex]\vec{A} + \vec{B} = \vec{C}[/tex]. Their magnitudes are related by [tex]\vec{A} - \vec{B} = \vec{C}[/tex]. Explain how this is possible.
The Attempt at a Solution
Vector [tex]\vec{B} = 0\hat{_i} + 0\hat{_j} + 0\hat{_k}[/tex]This was a question on my quiz. I received no credit for my solution. After class, I asked the professor why my solution was wrong and he then told me that since the vector I chose had a magnitude of zero, it did not exist. I argued my point a bit, but soon gave up. I was wondering, do zero vectors exist? I found another solution to the problem, but had not written it on my quiz:
The Attempt at a Solution
Vector [tex]\vec{B}[/tex] is antiparallel to [tex]\vec{A}[/tex]
Any help would be greatly appreciated!
