alleryA vector multiplied by a scalar stays collinear with the:
AThe zero vector
BOriginal vector
CUnit vector k
DThe x-axis line
Answer & Solution
Correct answer: B. Original vector
1. Scaling does not turn a vector off its line.
2. It only changes the length and possibly the sense.
3. So the result is collinear with the original.
