1.	Which of the following qauntities is dependent of the choice of orientation of coordinates axes?
Answer» `vecA + vecB` `A_(x) + B_(y)` `\|vecA + vecB\|` Angle between `vecA and vecB` SOLUTION :A vector, its magnitude and the angle between two vectors do not depend on the choice of the orientation of the coordinate axes. `vecA + vecB, \|vecA + vecB\|`,angle between `vecA and vecB` are independent of the orientation of the coordinate axes. but the QUANTITY `A_(x) + B_(y)` depends upon the magnitude of the COMPONENT along x and y-axes, SOIT will change with change in coordinate axes.
