Vector Algebra Question 308

Question: If a and b are two non-zero and non-collinear vectors, then a + b and a ? b are

[MP PET 1997]

Options:

A) Linearly dependent vectors

B) Linearly independent vectors

C) Linearly dependent and independent vectors

D) None of these

Show Answer

Answer:

Correct Answer: B

Solution:

  • Since $ \mathbf{a} $ and $ \mathbf{b} $ are non-collinear, so $ \mathbf{a}+\mathbf{b} $ and $ \mathbf{a}-\mathbf{b} $ will also be non-collinear. Hence, a + b and a ? b are linearly independent vectors.
