How does multiplying a vector by a scalar value of 2π change the vector?

A. The vector will not change direction but will decrease in magnitude.
B. The vector will change direction and decrease in magnitude.
C. The vector will not change direction but will increase in magnitude.
D. The vector will change direction and increase in magnitude.

C. The vector will not change direction but will increase in magnitude.

When a vector is multiplied by a scalar value of 2π, it simply scales the magnitude of the vector by a factor of 2π while keeping the direction the same.
