What is the correct formula for relative velocity of a body A with respect to B?(a) Vector VR = Vector VA – Vector VB(b) Vector VR = Vector VA + Vector VB(c) Vector VR = Vector VA x Vector VB(d) Vector VR = Vector VB – Vector VAI have been asked this question in an online quiz.My query is from Motion in a Straight Line topic in portion Motion in a Straight Line of Physics – Class 11

Answer»

Correct answer is (a) VECTOR VR = Vector VA – Vector VB

For explanation I would say: The relative velocity of one BODY with respect to another body can be found out by subtracting their respective velocities in respective ORDER. This rule applies not only to velocity, to all other vector QUANTITIES.
