### Physics

Multiple Choice Question Based on Passage
Relative Velocity
If two objects A and B are moving in a straight line with velocities VA and VB respectively, the relative velocity of object A with respect to object B is given by VAB = VA - VB
It follows that the relative velocity of object B with respect to A will be VBA = VB - VA
If objects A and B are moving along different directions in a plane, the relative velocity of one object with respect to the other is found by using the parallelogram law of vector addition. To find VAB, we find the resultant of vectors VA and - VB. To find VBA, we find resultant of vectors VB and - VA.
