Find a vector which is perpendicular to the plane

  1. Nov 9, 2009 #1
    1. The problem statement, all variables and given/known data
    the vectors a and b


    2. Relevant equations
    find a vector which is perpendicular to the plane containing vectors a and b


    3. 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....?

    Re: Vectors

    Yes, that's a good one.

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

    Re: Vectors

    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.
