Homework Help: 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?


    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.
