" A vector is not changed,if "

(A) : A vectors will not change when the fram of reference in which it is existing is rotated . (R) : A scalar quantity may (or) may not be independent of arientation of frame of reference :

A vector may change if :

(A): The direction of velocity vector remains unchanged though the coordinate system is changed (R) : The direction of real vector is independent of coordinate system

(A): The direction of velocity vector remains unchanged though the coordinate system is changed (R): The direction of real vector is indepen dent of coordinate system

An impules is supplied to a moving object with the force at an angle 120^(@) with the velocity vector. The angle between the impulse vector and the change in momentum vector is

Is a vector necessarily changed if it is rotated through anangle?
