Expert Solution
Step 1
Physics homework question answer, step 1, image 1

When we represent two vectors in cartesian co-ordinate then the positions of vectors be:

                   OB=bi^

                   OA=acosθ i^ +asinθ j^

When we apply Vector addition then 

                   AB=OA- OB

                  AB=acoθ i^ + asinθ j^ -bi^AB =acosθ -b i^ +asinθj^
