Question

The two vectors A and B that are parallel to each other are:
(A) Ā=3i+6j+9K, B=i+2j+3k
(B) Ā=3i - 6j+98, B=i+2j+3k
(C) Ā=i+2j+3k, B=i+2j – 3k
(D) Ā=3i +6j -9KB-1 -2j- 3k​

Answer 1

Answer:

Any quantity that has both direction and magnitude is called a vector quantity. If the quantity has only magnitude and no direction, then it is a scalar quantity. , i.e. B vector is a multiple of vector A. Therefore they are parallel to each other.
