Question

Which if the following is an accurate statedment?

a.) the magnitude of a vector can be zero even though one of its components is not zero.

b.)the magnitude of a vector is independent of the coordinate system used.

c.) even though two vectors have unequal magnitudes, it is possible that their vectors sum is zero

d.)Rotating a vector about an axis passing through the tip of the vector does not change the vector

e.) it is possible to add a scalar quantity to a vector

Answer 1

a) F. When the magnitude of a vector is zero, the non-zero direction is meaningless.
b) T
c) F. A + B = 0 means A = -B
d) F. Think about rotating a vector around x-axis.
e) F. Not defined.
