If the vectors `vec(k)and vec(A)` are parallel to each other, what is `k vec(k)xxvec(A)` equal to ?

A

`k^(2)vec(A)`

B

`vec(0)`

C

`-k^(2)vec(A)`

D

`vec(A)`

Text Solution

Verified by Experts

The correct Answer is:
B

Given , `vec(k) and vec(A)` are parallel vectors.
we know, cross product of parallel vectors is `vec(O)`.
