1. The problem statement, all variables and given/known data the problem is given in the attachment 2. Relevant equations basic knowledge of ac circuits and phasor diagrams 3. The attempt at a solution for point A , i calculated the potential easily. and for point B , i calculated the potential using phasor relationship .. now after doing VA - VB, i got the relation that its modulus will first decrease and then eventually increase but in the answer given is that modulus of VA - VB will remain unchanged.
