A "L" shaped conducting rod ABC is lying in xy-plane and moving with velocity $\overrightarrow{V}=V_0\hat{i}+3V_0\hat{j}$ as shown in the figure. There exist a non-uniform magnetic field which depends on x and y co-ordinate as $\overrightarrow{B}=\frac{B_0}{L_0}\left(x+y\right)\left(-\hat{k}\right)$, where $B_0$ and $L_0$ are positive constants with proper dimensions. If $V_P-V_Q$ represents the motional induced emf between point P and Q. Then choose the CORRECT option(s).
