A(vector) + B(vector)=2 i and A(vector) - B ( vector) = 4 j then angle between A and B is ? Share with your friends Share 0 Vijay Shankar Yadav answered this Dear Student, we have A→+B→=2i^--1A→-B→=4j^--2from 1 and 2 we getA→=i^+2j^B→=i^-2j^A→∘B→=i^+2j^∘i^-2j^ABcos(θ)=-355cos(θ)=-3cos(θ)=-3/5θ=cos-1-35 Regards 0 View Full Answer
