The velocity of a car A is to 5î. The velocity of another car B is 22î – 7ĵ. What is the relative velocity of A with respect to B?(a) -17î + 7ĵ(b) 7î + 17ĵ(c) -7î + 17ĵ(d) -17î + 7ĵI have been asked this question by my college director while I was bunking the class.The question is from Motion in a Plane topic in chapter Motion in a Plane of Physics – Class 11

Answer»

Right choice is (a) -17î + 7ĵ

To explain I would SAY: The FORMULA for calculating relative velocity of a body with respect to another body is- relative velocity = Velocity VECTOR of A – Velocity vector of B. Hence, here, the relative velocity = velocity of B – velocity of A = -17î + 7ĵ.
