Vectors- scalar products - statements true/false

  1. Sep 11, 2010 #1
    1. The problem statement, all variables and given/known data

    7 statements about vectors. Which two statements are incorrect?

    Question:

    A The result of the vector product of two vectors is a scalar quantity.
    B A vector can have a magnitude of zero.
    C A vector is completely specified by its magnitude and direction.
    D Two vectors can only be added if they have the same direction.
    E The scalar product of two vectors is a scalar quantity.
    F Multiplying all the components of a vector by a constant is equivalent to multiplying the vector by that constant.
    G Given a vector’s magnitude and direction, its components can always be calculated.

    2. Relevant equations



    3. The attempt at a solution

    statement B is incorrect and D i think.
    as vectors cannot have magniute of zero and vectors in different directions can be added.

    You're going to get the answer by popular vote?? What do you think about the proposed two answers and why?
