Homework Statement

the vectors a and b

Homework Equations

find a vector which is perpendicular to the plane containing vectors a and b

The Attempt at a Solution

do i find the vector product of a and b and then find something that's parallel to that or...?

 

[CompuChip]

Yes, that's a good one.

Hint: note that the vector v is parallel to the vector v.

 

[Seannation]

The vector product will give you a vector that is perpendicular to both a and b. This should be sufficient to answer the question, I don't think you need to find another which is parallel to this vector.
