Question

Is a vector necessarily changed if it is rotated through an angle?

• A. True
• B. False
• C. Can't Say
• D. None of These

Answer 1

The correct option is B

False

If a vector is rotated by any angle which is not a multiple of ${360}^{\circ }$ or $2\pi$ radians, then it is different. But if rotated through a multiple of ${360}^{\circ }$, it remains the same. As it is simply making full circles, the direction will be the same as the initial direction.
