Which of the following qauntities is dependent of the choice of orientation of coordinates axes?

Options

A. `vec(A)+vec(B)`
B. `A_(x)+B_(y)`
C. `|vec(A)+vec(B)|`
D. Angle between A and B

Answer

B

Explanation

A vector, its magnitude and the angle between two vectors do not depend on the choice of the orientation of the coordinates axes. So `vec(A)+vec(B),|vec(A)+vec(B)|`, angle between `vec(A) and vec(B)` are independent of the orientation of the coordinates axes.
