Question

Show that A=-2i+3j+k and B=-6i+9j+3k are collinear vector

Answer 1

B = 6i + 9j + 3k = 3(2i + 3j + I

=> B = 3A

Hence, they are in same direction .Hence, there are collinear as parallel vectors are colinear.

Answer 2

Answer:

B=3A

Explanation:

from vector b when we take 3 common out then we get it as B=3(-2i+3j+k)

i.e. B=3A therefore it is collinear
