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.
