6. Show that the vectors 2i-3j+4k and -6i+9)-12k are parallel to each other

Answer»

for a vector be parallel to other.. , it Should be represented in the form of K times the other vecr

here -6i+9j-12k = -3(2i-3j+4k) that is exactly k(=-3) times the earlier one..

so, both the vectors are parallel.

Do u have any other answers
