Homework Statement
Three vectors A, B, and C add together to yield zero: A + B + C = 0. The vectors A and C point in opposite directions and their magnitudes are related by the expression: A = 2C. Which one of the following conclusions is correct.
A. B and C have equal magnitudes and point in the same direction.
B. A and B have equal magnitudes and point in opposite directions.
C. B and C have equal magnitudes and point in opposite directions.
D. A and B point in the same direction, but A has twice the magnitude of B.
E. B and C point in the same direction, but C has twice the magnitude of B.
Homework Equations
A + B + C = 0
A = 2C
The Attempt at a Solution
I've never been good at these types of problems. They feel like brain teasers. I was thinking about replacing A, B, and C with numbers. A being equal to 2 times C. But that didn't work out as smoothly as I had hoped.
Um...help, please?
