Question

if two vector 3i +3j+9k and I aj 3k are parallel then the value of a is​

Answer 1

Thus For two vectors to be parallel, the components of the vector should be known as each other. ... Yes these are parallel vectors because if we multiple in second with 3, we get b= 3i+6j+9k which is Vector a=2i+3j+4k, and vector b=3i+4j+5k.
