The velocity of a car A is to 5î + 11ĵ. The velocity of another car B is 11î + 5ĵ. What is the relative velocity of B with respect to A?

(a) 6î – 6ĵ

(b) 11î + 5ĵ

(c) 6î + 6ĵ

(d) 5î + 5ĵ

I got this question in homework.

My doubt is from Motion in a Plane topic in section Motion in a Plane of Physics – Class 11

Best answer
The correct answer is (a) 6î – 6ĵ

Easiest explanation: 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 = 6î – 6ĵ.
