Question

If  vector a and vector b are two collinear vectors, then which of the following are incorrect:
A. b = λa,  for some scalar λ

B. a=b

C. the respective components of a and b  are proportional

D. both the vectors a and b  have same direction, but different magnitudes

Answer 1

If vector a and vector b  are two collinear vectors, then they are parallel.
Therefore, we have:

Hence, the statement given in D is incorrect.
The correct answer is D.
