Two vectors \vec{A}  and \vec{B} inclined at an angle \theta have a resultant \vec{R}\ which makes an angle \alpha with\vec{A}. If the direction of\vec{A}and \vec{B} are interchanged, the resultant will have the same.

Option: 1

Direction 

 


Option: 2

Magnitude


Option: 3

Direction as well as magnitude

 


Option: 4

None of these
