This is a problem of geometry. So, a scalar has magnitude (size) only. Therefore, we can conclude that ta scalar is just a number. If we multiply a vector by a scalar it is called scaling a vector, because we change how big or small the vector is. Given that 2π is a positive scalar then the answer is:
C) The vector will not change direction but will increase in magnitude.
This is true because:
