The magnitude of a vector can be different in different coordinate systems. The magnitude of a vector can be different in different coordinate systems. True False

False.

Explanation:

We usually define vectors in terms of its magnitude and their orientation. Magnitude and direction does not vary with the change of a coordinate system as they are independent of coordinates and will remain the same. So it does not matter what your choice of a coordinate system is, it will not effect its direction and magnitude. However you can resolve the vector in to its components if you want.
