Hi folk, I need help.
I encountered a question in my high school exam that was
" The resultant of two anti-parallel vectors [b]A[/b] and [b]B[/b] is:
2) [b]A-B[/b] "
What is the correct answer?
I was told that it is A-B, but how could it be A-B, when resultant it self means that it is bascially the addition of two vectors.
If B vector is anti to A, then it should be -B as convention, but what if we say that -[b]B[/b]=[b]C[/b]
Then it becomes A+C, means we have to add them both to get answer.
I'm stuck please help me out.
