Question

WHAT IS THE DIRECTION OF A NULL VECTOR ?

Answer 1

SO IA AM SAYING THAT IT IS A VECTOR BUT IT HAS NO DIRECTION .IS IT NOT VIOLATING THE BASIC IDEA OF VECTORS ?

Answer 3

not at all ...i must have said that this way
"A null vector has a direction but its arbitrary ,we cannot specify it"

Answer 4

O THEN IT IS OK

Answer 5

:)

Answer 6

It doesn't have a direction because the magnitude of all of the components is 0. That doesn't conflict with the definition of a vector at all in my opinion.

Answer 7

A zero(null) vector has arbitrary direction, but is orthogonal (i.e. perpendicular, normal) to all other vectors with the same number of components.

Answer 8

@stormfire1 pls crct urself

Answer 9

Straight from wikipedia?

I guess that's right but in theory, a line with no magnitude is a point and a point doesn't have a direction!

Answer 10

ya but we have an arbitrary direction defined for it so u cant say no for sthng which ahs been defined

Answer 11

I stand corrected...by definition the direction is arbitrary.

Answer 12

:)

Answer 13

I still don't like it :)

Answer 14

i have to wonder what is meant by "null vector". If it means a vector in the null space; then it is perpendicular to the colSpace ... but that is a mathical idea
