Question
Part A Which of the following is an accurate statement? O Rotaing a vector about an axis passing through the tip of the vector does not change the vector 0 The magntude of a vector is independent of the coordinate system used O Even though two vectors have unequal magnitudes, it is possible that ther vector sum ls zero O The magnitude of a vector can he zero even though one of its components is not zero G inis possible to add a scalar qusntity to a vector Submit Provide Feedback O Type here to searchExplanation / Answer
1.) False Rotating a vector change its direction.
2.) True
In the Cartesian coordinate system {x, y, z}, the magnitude requires a computation
= {x² + y² + z²}
In the polar (or spherical ) coordinate system {, , }, the magnitude is available by inspection .
But the magnitude is always the same.
3.) False If the vectors has unequal magnitudes it is imposible to get their sum zero.
4.) False If one of the component is non zero then we will get some value of magnitude which will not be equal to zero.
5.) False
